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

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

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

The filter whose TF of the system is  isSelect one:a. All pass Filter  b. Band pass Filterc. Low pass Filterd. High pass Filter

A low pass filter with a cut-off frequency of 30 Hz is cascaded with a high pass filter with a cut off frequency of 20 Hz. The resultant system of filters function as

The Q of a band-pass filter depends on
