Physics - Semiconductors Question with Solution | TestHub

The truth table for a two-input Ex-OR (Exclusive-OR) gate is as follows:
Input A = $0$, Input B = $0$ $\Rightarrow$ Output = $0$
Input A = $0$, Input B = $1$ $\Rightarrow$ Output = $1$
Input A = $1$, Input B = $0$ $\Rightarrow$ Output = $1$
Input A = $1$, Input B = $1$ $\Rightarrow$ Output = $0$

The output is 'HIGH' or '$1$' only when exactly one of the inputs is '$1$' (which is an odd number of 'HIGH' inputs). In general, for any number of inputs, an Ex-OR gate gives a 'HIGH' output if and only if an odd number of its inputs are 'HIGH'. Hence, it is also known as an odd parity generator.

Answer: Ex-OR gate
