The quality factor (Q) of a filter provides a measure of:

a. how much signal is attenuated by the filter

b. how selective the filter is

c. how much ripple is produced in the passband

d.how much attenuation the filter has at the cutoff frequency

Solution

Ans) b. how selective the filter is

Reason: As per the definition of quality factor Q =fc/f, where bandwidth= f,fc=center frequency Higher the Q lesser the bandwith and filter becomes more selective and for lower Q vice-versa happens
