1.	Minimum time required for magnitude change or phase change is called as(a) Shift time(b) Coherence time(c) Delay time(d) None of the mentionedThe question was asked in an interview.The above asked question is from Signal Time Spreading in division Fading Channels of Digital Communications
Answer» Correct option is (b) Coherence time The best I can explain: Coherence time is the minimum time required for MAGNITUDE or PHASE CHANGE of the channel to BECOME uncorrelated from the previous value.
