The ratio of the filter bandwidth at -60db and -6db amplitude response

1.	The ratio of the filter bandwidth at -60db and -6db amplitude response point is called as _____(a) Half point factor(b) Normalized factor(c) Shape factor(d) None of the mentionedThe question was posed to me in my homework.My enquiry is from Baseband Systems and Signal Transmission through Linear Systems in portion Signals and Spectra of Digital Communications
Answer» Right choice is (c) Shape FACTOR Explanation: Shape factor is a measure of how WELL realizable filter APPROXIMATES to ideal filter. It is the ratio of filter bandwidths -60db and -6DB amplitude POINTS.
