Question

The circuit given below represents which of the logical operations?

A. AND
B. NOT
C. OR
D. NOR

Answer 1

Hint: To solve this question one must know about the given gate in question as the gates above are NAND gates. Then one can easily solve this question. Here to solve this question we will take input and see the result and depending upon the output we will determine the circuit id of which operator.

Complete Step By Step Answer:
Let us understand NAND gate as we know that in NAND gate whatever we take input the result becomes, let us take input, $ A $ and $ B $ the output is $ \overline {A \cdot B} $ .Also called the logical expression of a NAND gate is given by $ Y = \overline {A \cdot B} $ .
Similarly, here we took input as $ A $ and $ B $ and then we know as a NAND gate the output will come as $ Y = \overline {A \cdot B} $ and then this acts as input and again goes in NAND gate and the we will get the output as $ Y = \overline {\overline {A \cdot B} } $ and this is nothing but $ A \cdot B $ which means the output is AND gate.

Note:
Note that in an AND gate the logical expression of an AND gate is given by $ Y = A \cdot B $ .
Logic gates are circuits with determining components like transistors and diodes. These transistors serve as a switch, adding the voltage signals that pass through them. RAM is extensively used in computers, phones, and other devices, but it is only a collection of flip flop logic gate circuits that allows us to store data. Examine the circuit diagram carefully to identify the gates utilised in queries like these. Apply the appropriate actions to the gates.
