The electronic filter is usually a frequency selective network that passes a specify band of frequencies and ----------------- signals of frequencies outside this band

What are filters created by using resistors and capacitors or inductors and capacitors called

A Circuit that uses an amplifier with passive filter elements is called as

Active filters are usually fabricated by

An electrical filter is a

The problem of passive filters is overcome by using

Filters are classified as:

_________ is the frequency at which the filter starts to attenuate the signal

_______ is how quickly the filter attenuates frequencies beyond the cut-off
