Which of the following statement is true, if a return echo arrives aft

1.	Which of the following statement is true, if a return echo arrives after the allocated pulse interval?(a) it will interfere with the operation of a transmitter(b) the receiver might be overloaded(c) overlap of signals(d) target will appear closer than it really isThis question was addressed to me in a national level competition.My query is from Noise for SSB-SC topic in section Noise of Analog Communications
Answer» RIGHT answer is (d) target will appear closer than it REALLY is Easiest explanation: If a return ECHO arrives after the allocated pulse INTERVAL then the target will ALWAYS appear closer than it really is.
