The critical frequency is defined as the point at which the response drops from the passband is

The Q of a band-pass filter depends ona.the center frequency and the bandwidthb.only the center frequencyc.only the bandwidthd.the critical frequencies

When a low-pass and a high-pass filter are cascaded to get a band-pass filter, the critical frequency of the low-pass filter must bea.None of theseb.less than the critical frequency of the high-pass filterc.equal to the critical frequency of the high-pass filterd.greater than the critical frequency of the high-pass filter
