Question

Quizplus · Accepted Answer

Filters are designed to eliminate unwanted frequencies from signals and can be used to separate desired signals from undesired signals, block interfering signals, and enhance speech and video. Amplifiers are designed to increase the amplitude or power of a signal, while attenuators are designed to decrease the amplitude of a signal. Oscillators generate periodic, alternating signals.
