What the main advantage of PCM?(a) can travel small distances(b) higher bandwidth(c) lower noise(d) good receptionI have been asked this question by my school teacher while I was bunking the class.Query is from Modulation of VSB Modulated Wave in division VSB Modulation of Analog Communications

Answer»

The CORRECT OPTION is (c) lower noise
