D) regenerative.

Question

Quizplus · Accepted Answer

The input to a negative-feedback amplifier can be either voltage or current, depending on the specific circuit design. This flexibility is one of the advantages of negative feedback, as it allows for a wide range of input signals to be processed. The feedback loop then works to attenuate any deviations from the desired output signal, providing stability and accuracy to the amplifier circuit. The input signal is not regenerative, as it is simply the signal being processed by the amplifier, rather than a signal that is fed back to the input in order to amplify it further.
