1.	In M-ary PSK, the carrier ___________ takes one of M possible values.(a) Amplitude(b) Frequency(c) Angle(d) PhaseThis question was addressed to me at a job interview.I need to ask this question from Combined Linear and Constant Envelope Modulation Techniques topic in portion Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The CORRECT OPTION is (d) Phase To ELABORATE: In an M-ary PSK, the carrier phase takes ONE of the M possible values. The possible values of phase are θi=2(i-1)/M, where i=1,2,…….,M.
