A desirable modulation scheme provides _________ bit error rates at __

1.	A desirable modulation scheme provides _________ bit error rates at __________ received signal to noise ratios.(a) Low, low(b) Low, high(c) High, high(d) High, lowI have been asked this question by my school principal while I was bunking the class.I'm obligated to ask this question of Digital Modulation topic in section Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Correct option is (a) Low, low The explanation is: A desirable modulation scheme provides low bit error rates at low received signal to noise ratios. They PERFORM WELL in MULTIPATH and fading conditions, occupies a minimum bandwidth and is easy and cost effective to IMPLEMENT.
