Question

Which gate is called the anticoincidence and coincidence gate respectively?

• A. XNOR and XOR
• B. AND and OR
• C. OR and AND
• D. XOR and XNOR

Hint:

XOR/XNOR Functions. XOR (Anticoincidence): Output is 1 if inputs differ. XNOR (Coincidence/Equality): Output is 1 if inputs are the same.

Answer 1

The Correct Option is D

- The XOR (Exclusive OR) gate produces a HIGH output only when its inputs are different (not the same, or not coincident)
Therefore, it is called the anticoincidence gate
- The XNOR (Exclusive NOR) gate produces a HIGH output only when its inputs are the same (coincident)
Therefore, it is called the coincidence gate
The question asks for anticoincidence and coincidence gates, respectively
This corresponds to XOR and XNOR
