The voltage gain of a circuit known as a sign changer can be varied from -1 to 1.

Question

Quizplus · Accepted Answer

A sign changer circuit can invert the input signal and output a negative version of the input signal with the same magnitude. Therefore, it has a voltage gain with a maximum value of -1. It can also provide a positive version of the input signal with the same magnitude, resulting in a voltage gain with a maximum value of 1. The voltage gain can be varied between -1 and 1 by adjusting the circuit parameters.
