The signal processor that increases all negative dBm power levels and at the same time decreases all positive dBm power levels is:
A) a signal compressor
B) a signal expander
C) a phase-locked loop
D) a linear amplifier

Question

Quizplus · Accepted Answer

A signal compressor is designed to reduce the dynamic range of an audio signal. It increases the level of signals below a certain threshold (negative dBm levels) and decreases the level of signals above this threshold (positive dBm levels), effectively compressing the dynamic range of the signal.
