1.	The name minimum phase shift keying implies minimum _________(a) Frequency separation(b) Amplitude separation(c) Phase change(d) Amplitude deviationI had been asked this question by my school teacher while I was bunking the class.This interesting question is from Constant Envelope Modulation topic in division Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Right answer is (a) Frequency separation To EXPLAIN I WOULD SAY: The name minimum phase shift keying implies minimum frequency separation, i.e. the bandwidth that allows orthogonal detection. A modulation index of 0.5 corresponds to the minimum frequency spacing that allows TWO FSK SIGNALS to be coherently orthogonal.
