Modulation process includes(a) Analog to digital conversion(b) Digital

1.	Modulation process includes(a) Analog to digital conversion(b) Digital to analog conversion(c) All of the mentioned(d) None of the mentionedThe question was posed to me in my homework.The question is from Modulation and Multiplexing in section Modulation and Coding Trade-off of Digital Communications
Answer» Correct answer is (b) Digital to analog conversion To EXPLAIN I WOULD say: Modulation procedure includes digital to analog conversion which PRODUCES a continuous time signal that can be SENT through the CHANNEL.
