1.	Which is the primary cost for degradation of error performance?(a) Loss in signal to noise ratio(b) Signal distortion(c) Signal distortion & Loss in signal to noise ratio(d) None of the mentionedI had been asked this question in final exam.My question is based upon Link Budget Analysis topic in portion Communication Link Analysis of Digital Communications
Answer» CORRECT answer is (c) Signal DISTORTION & Loss in signal to noise ratio For explanation I would say: There are two primary causes for the DEGRADATION of ERROR performance. They are loss in signal to noise ratio and the second is signal distortion caused by intersymbol INTERFERENCE.
