Question

The logic operation (OR, AND, NOR or NAND) carried out by the following circuit is 

• A. AND
• B. NOR
• C. OR
• D. NAND

Hint:

In digital logic, each gate has a distinct symbol. Familiarize yourself with these symbols to easily identify the operation.

Answer 1

The Correct Option is C

The given circuit appears to be a representation of a logic gate operation. In digital electronics, several logic gates like AND, OR, NOT, NAND, NOR exist. Each of these gates performs a basic but essential function in digital circuit design.

Let's analyze the circuit step-by-step:

1. The image shows two inputs, A and B, going into a shaped gate.
2. The shape of this gate resembles the symbol for an OR gate.
3. An OR gate outputs true (or high, 1) when at least one of its inputs is true (or high, 1).

Hence, the logical operation performed by the circuit shown in the image is an OR operation.

Let’s confirm by evaluating the options:

• AND: This gate outputs true only when both inputs are true, which does not match the circuit.
• NOR: This is the inverse operation of OR, outputting false when any input is true, which does not match the circuit.
• OR: Matches the observed operation as at least one input being true results in the output being true.
• NAND: This is the inverse operation of AND, which does not match the circuit.

Based on the analysis, the correct answer is an OR operation.
