1.	According to Nyquist, the impulse response of the overall communication system should have ______ decay with _______ magnitude for sample values not equal to zero.(a) Fast, small(b) Slow, small(c) Slow, large(d) Fast. LargeThe question was posed to me at a job interview.This is a very interesting question from Pulse Shaping Techniques in section Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Correct option is (a) Fast, small To explain: According to Nyquist, the impulse response of the overall communication SYSTEM should have fast DECAY with small magnitude for sample values not EQUAL to zero. If the channel is ideal then it should be possible to realize APPROXIMATE shaping filters at both transmitter and receiver.
