Question

in the double - ended differential mode, select one: a. a signal is applied between the two inputs b. the gain is 1 c. only one supply voltage is used d. the outputs are different amplitudes

Explanation:

Double-ended differential mode defines that an input signal is applied across the two input terminals of a differential amplifier. Option b is incorrect as gain is not fixed at 1. Option c is wrong because differential amplifiers typically use dual supply voltages. Option d is incorrect since outputs have equal amplitude (opposite phase) in this mode.

Answer:

a. a signal is applied between the two inputs
