Plzz guys tell short tricks to remember Logic Gates ( Equation with Symbol )
Answers
Explanation:
I think you are talking about the truth tables of the different logic gates. You DO NOT memorize those tables. The very names of the gates will help you construct the table in 5 seconds the moment you need them. This is how you do it:
NOT gate: This is a single input gate. If the input is 'True' (1) then the output is NOT 'True' (NOT 1), that is 'False' (0). Vice versa, if the input is 'False', the output will be 'True'
AND gate: Unless both the logic inputs are not 'True' (i.e. 1), the output cannot be 'True', because that is what AND means: A compound statement made by using the preposition AND cannot be 'True' unless both the statements comprising it are 'True'. For example, the statement 'Peter is having sandwich and Paul is having tea' will not be true unless both of them are actually having their respective items. So A and B (i.e. AB) is 1 only if A=1 and B=1, else 0.
OR gate: As the name suggests, if either of the two inputs (statements) is 'True', the output (compound statement) will be 'True'. If both of them are 'False', only then will the output be 'False'.
XOR gate: "XOR" stands for 'Exclusive OR', which means that the output will be 'True' if ONLY ONE of the two inputs is 'True' and the other is 'False' but not when both are 'True'. In real life, we generally use the word 'either' to talk about such situations. So when you say that you want either tea or coffee, you mean that you want only one of them, and not both, which is the XOR operation.
The Complementary gates (NAND, NOR, XNOR): NAND stands for 'NOT AND', NOR for 'NOT OR' and XNOR for 'NOT XOR'. These gates can be simply understood as the normal gates followed by the NOT gate. So if you want the truth tables for these gates, write the output for the normal gates (AND, OR and XOR) and then take the NOT of the output.
It may take some time initially to construct the truth tables, but with repeated usage, you will able to do it in your sleep ;) And again, do not memorize else you are insulting your brain!
