Filters designed to exhibit low impedance to frequencies on either side of their resonant frequency are _____ filters.
A) low-pass
B) high-pass
C) bandpass
D) band-rejection

Question

Quizplus · Accepted Answer

Band-rejection filters, also known as notch filters, are designed to block frequencies within a certain range while allowing frequencies outside of that range to pass through, thus exhibiting low impedance to frequencies on either side of their resonant frequency.
