Q2. What is a logic gate?

Answer: When we deal with logical circuits (as in computers), we not only need to deal with logical functions; we also need some special symbols to denote these functions in a logical diagram. There are three fundamental logical operations, from which all other functions, no matter how complex, can be derived. These functions are named and, or, and not. Each of these has a specific symbol and a clearly-defined behavior, as follows: | | The AND GateThe AND gate implements the AND function. With the gate shown to the left, both inputs must have logic 1 signals applied to them in order for the output to be a logic 1. With either input at logic 0, the output will be held to logic 0.If your browser supports the Javascript functions required for the demonstrations built into this page, you can click the buttons to the left of the AND gate drawing to change their assigned logic values, and the drawing will change to reflect the new input states. Other demonstrations on these pages will work the same way.There is no limit to the number of inputs that may be applied to an AND function, so there is no functional limit to the number of inputs an AND gate may have. However, for practical reasons, commercial AND gates are most commonly manufactured with 2, 3, or 4 inputs. A standard Integrated Circuit (IC) package contains 14 or 16 pins, for practical size and handling. A standard 14-pin package can contain four 2-input gates, three 3-input gates, or two 4-input gates, and still have room for two pins for power supply…...

...Throughout 1980’s, several pieces of evidence were revealed that led the NCAA to believe recruiting sanctions were violated at Southern Methodist University. The substantial evidence relates to an aggressive and illegal recruiting practice that attracted top recruits to attend and play football at SMU. The sequence of evidence abstracted from the University is listed as follows: • 1980: A victory over Texas after a 14 game losing streak between the two schools sparked significant media attention and brought suspicion on SMU's recruiting practice. • 1981: A ten win season and a victory over Arkansas earned SMU the Southwest Conference Championship. • 1981: The departure of Ron Meyer led to national attention that violations were close to being revealed. Bobby Collins was hired as the new head football coach. • Mid 1980's: Sean Stopperich, a former player, claims SMU Boosters moved his family from Pittsburg to Texas, found his father a job, and paid for certain expenses. • Mid 1980's: David Stanley, a former player, claims to receiving payments to play football at SMU. • Mid 1980's: A televised interview revealed handwritten envelopes from SMU’s Athletic Director, Henry Lee Porter, addressed to David Stanley’s home. • Mid 1980's: Bobby Collins, Henry Lee Porter, and the University’s President resigned from the University due to the allegations of NCAA recruiting violations. The evidence presented suggests that a predication of NCAA recruiting violations had......

...Logical Concepts an overview What is logic? •  Logic is the science of reasoning, •  which is to say: the academic discipline that investigates reasoning. What is reasoning? •  reasoning is inferring (deducing) •  to infer is to draw conclusions (output) from a premise or set of premises (input). An Example of Reasoning You see smoke And you infer That there is fire (input) (deduce) (output) Another example of Reasoning You count 19 people in a group; which originally had 20 people in it; and you infer that someone is missing (input) (input) (deduce) (output) The Basic Idea Logic evaluates reasoning in terms of arguments. What is an argument? •  The word “argument” can mean many different things depending on the context. •  But for the purposes of logic, the term “argument” means something very specific: What is an argument? •  an argument is a collection of statements, one of which is designated as the conclusion, and the remainder of which are designated as the premises. •  Important note: premises are always intended to provide support or evidence for the conclusion, but they don't always succeed. (It’s still an argument either way.) What is a statement? •  A statement is a declarative sentence, •  i.e., a sentence that is capable of being true or false. •  For example: The door is closed. •  Other kinds of sentence are not capable of being true or false: •  Interrogative sentences are inquiries for information: Is the......

...LEADERSHIP REFLECTIVE JOURNAL 6 In this tutorial, I learned about Appreciate Inquiry, which is a practical framework of emotion in leadership. Appreciate inquiry is an approach from Positive Organisational Scholarship (POS), which focuses on companies creating positive work life and performance. The four key components of positive organizational scholarship (POS) are self-efficacy, hope, optimism and resiliency. I practiced AI by following 3 steps consisting of Positive priming, Group discussion and provided positive answer to the question Student contribution in tutorials on the BSc in Business management and how it can be even better, even stronger. The tutorial delivered an emotion- based approach that leader may adapt to implement change in organisation. Through the Appreciate Inquiry, a leader as well as subordinates should have the ability think more positively and thus be able to manage organisational performance through positive changes. The practice of Appreciate Inquiry also introduces a new approach to understanding of emotion and leadership; it concentrates more on the positive emotion and cognitive process rather than the negative sides as it helps to identify the strengths and opportunity Being in AI mode; I felt that thinking positively did provide a number of advantages. The AI allowed me to minimise or ignore all the negative factors or counter argument for every point I make for the improvement in Business Management improvement issue. This allowed me......

The maximum possible number of states (maximum modulus) of a counter is 2n. Where n is the number of flip-flops in the counter. TRUNCATED SEQUENCES:  Counters can also be designed that have a number of states in their sequence that is less than the maximum of 2n.the resulting sequence is called a truncated sequence. Muhammad Usman Arif 3 12/11/2013 ASYNCHRONOUS DECADE COUNTER:  To obtain a truncated sequence, it is necessary to force the counter to recycle before going through all of its possible states. For example, the BCD decade counter must recycle back to the 0000 state after the 1001 state. One way to make the counter recycle after the count of nine (1001) is to decode count ten (1010) with a NAND gate and connect the output the clear (CLR) input. 4 Muhammad Usman Arif 12/11/2013 2 12/11/2013 ASYNCHRONOUS DECADE COUNTER: 5 Muhammad Usman Arif 12/11/2013 PARTIAL DECODING:  Notice in the figure that only Q1 and Q3 are connected to the NAND gate inputs. This arrangement is an example of partial decoding; in which the two unique states (Q1 = 1 and Q3 =1 ) are sufficient to decode the count of ten because none of the other states (zero through nine)......

...Part one of the video opens up by telling viewers that Aristotle is credited with formalizing logic as a discipline. Viewers are directed to the aspect of what arguments are in the area of logic. Arguments are not heated exchanges or personal assaults, but however they are a group of statements. Statements are sentences capable of being true or false. An example of a statement is saying, “All cats are vicious animals.” The next topic that is brought up in part one of the video is the subject of inference. Inference is the reasoning process of an argument. Inference can be explicit (using premise and/or conclusion indicator words) and implicit (the reader has to catch the inference). Finally the video concludes with the point that there are four non-inferences commonly mistaken for arguments these are: advice, assertion, reports, and explanations. Part two of the formal logic video is the topic of inference. As stated in the early video inference is the reasoning process of an argument. Viewers are now introduced with the topic of deductive and inductive arguments. A deductive argument means that there is no possibility of the conclusion being false when the premises are true. Inductive arguments mean that the premises merely make the conclusion likely (conclusion “goes beyond” the premises). Lastly inductive forms are arguments based on signs, prediction, and generalization just to name a few. Part three of the video talks about validity, strength, soundness, and......

...1.2.1.AK Combinational Logic Design Introduction Combinational and sequential logic are the fundamental building blocks of digital electronics. Combinational logic, which is sometimes referred to as "combinatorial logic”, is characterized by its output being a function of the current input value. A variety of different logic gates can be used to implement combinational logic circuits. Many of these gates will be studied in future units of this course. In this introductory unit, we will limit our designs to AND, OR, and INVERTER gates for the sake of simplicity. In this activity you will use the Circuit Design Software (CDS) to build and test your first combinational logic circuits. Equipment * Circuit Design Software (CDS) Procedure Now it’s time for you to implement your first AOI combinational logic circuit. The circuit that we will use for this purpose is a Car Safety Buzzer design.The design specifications are as follows: The buzzer is on whenever the door is open or when the key is in the ignition and the seat belt is not buckled. 1. Create a table that describes these design specification in terms of “highs” (1) and “lows” (0). This is when the sensor or indicator is active or not active. Seat Belt | 0 = SEAT BELT NOT BUCKLED | | 1 = SEAT BELT BUCKLED | Key | 0 = KEY NOT IN THE IGNITION | | 1 = KEY IN THE IGNITION | Door | 0 = DOOR IS NOT OPEN | | 1 = DOOR IS OPEN | Buzzer | 0 = BUZZER is OFF | | 1 = BUZZER is ON | 2.......

...Georgetown, Saudi international relations For many years, I have been interested in studying international relations. My interest in pursuing this field stems from several factors which have affected me. First, I have been exposed to international affairs throughout my life. With my father and two of my brothers in the Saudi Foreign Service, I have grown up under the shadow of inter-national affairs. Second, I am fascinated by history, economics, and diplomacy. I believe, through the study of international relations, I can effectively satisfy my curiosity in these fields. A third factor which has affected my interest in international relations is patriotism. Through the Foreign Service, I would not only have the opportunity to serve my country, but also have the chance to help bridge gaps between my country and others. Finally, as a Saudi living abroad, I have been bridging cultures throughout my life. This experience has taught me to look for differences to compromise and similarities to synthesize in order to balance different cultures. In short, I believe that my experiences in life, combined with a rigorous academic education, will enable me to pursue a successful career in the Saudi Foreign Service. Georgetown, Favorite class At St. Albans, especially in our later years, we are given the freedom to choose from a vast array of classes. Using this freedom, I have selected classes which have personal significance to me, regardless of difficulty or appearance on my......

... Logic Application After evaluating the game of “Guess your Card”, I assume that my cards could only be 4, 5, and 9. I came up with this logic by starting with Andy. I add all three numbers together from each player. Andy has the cards of 1, 3, and 7 with a sum of 11. Belle has the cards 3, 4, and 7 with a sum of 14, and Carol has the cards 4, 6 and 8 with a sum of 18. Since each player have a different sum I took the players with the highest sum which is Belle and Carol to see which player cards would add up with my cards. Next, Belle draw the question card, “of the five odd numbers”, how many different odd numbers do you see? She answer all of them. Only because the only odd numbers she see is from Andy and Carol which are 1, 3, and 7. That's how I came up with the numbers of 5 and 9. I then, add together 5 and 9 which is 14, let's not forget in the beginning I said the sums must add up to either 14 or 18. Since 5+9=14, and the smallest card is 1 so my cards must add up to more than 14. The sum of my cards must be 18. In order for me to find out what is my final card I must subtract 18 from 9 and 5 which gives me 4. You can also see why Andy knew what cards he had. He realize that the only odd numbers Belle could see from Carol and myself were 5 and 9, but yet she claim she could see all five odd numbers. So the remaining three: 1, 3 and 7 must have come from Andy himself. That's how he figure out what he had. The logic of......
