Quizplus · Accepted Answer

The response labeled "B" represents a Bessel response, which is characterized by its maximally flat group delay, ensuring that all frequency components of the signal are delayed by approximately the same amount, preserving the waveform shape of the signal being filtered. This is distinct from Butterworth (maximally flat magnitude response) and Chebyshev (ripples in the passband or stopband) responses.
