1.	M-ary signalling techniques are not sensitive to timing jitters.(a) True(b) FalseThis question was posed to me during an interview for a job.I want to ask this question from Combined Linear and Constant Envelope Modulation Techniques topic in section Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Right choice is (b) False The explanation: Timing errors increase when smaller DISTANCES between signals in the CONSTELLATION diagram are used. M-ary signalling TECHNIQUES are attractive for use in bandlimited channel, but are limited in their applications DUE to sensitivity in timing jitter.
