D)none of the above

Question

Quizplus · Accepted Answer

The upper cutoff frequency of a band-pass filter, formed by cascading a high-pass and a low-pass filter, is determined by the low-pass filter. This is because the low-pass filter limits the high-frequency components that can pass through, thus setting the upper frequency limit of the band-pass filter.
