The ratio of the 60 dB and 6 dB bandwidths for a ceramic filter is known as:
A) the roll-off rate of the skirt
B) the shape factor
C) the ripple amplitude
D) the quality factor

Question

Quizplus · Accepted Answer

The shape factor of a ceramic filter is defined as the ratio of the bandwidths at two different decibel levels, typically comparing the -60 dB bandwidth to the -6 dB bandwidth. This factor gives an indication of how sharply the filter transitions from its passband to its stopband, which is crucial in applications requiring precise filtering.
