Question

question 30
which logic function is represented by the equation abcd = x?
inverter
and
or
clock

Explanation:

The AND logic function outputs 1 (true) only when all input variables (A, B, C, D in this case) are 1. In Boolean algebra, the AND operation is represented by multiplication (e.g., \(ABCD\)). The inverter (NOT gate) inverts a single input. The OR function outputs 1 when at least one input is 1 (represented by addition in Boolean algebra, e.g., \(A + B+C + D\)). A clock is a timing signal in digital circuits, not a logic function related to this equation. So, \(ABCD = X\) represents the AND function.

Answer:

B. AND
