Which block or device does the data compression?(a) Channel encoder(b)

1.	Which block or device does the data compression?(a) Channel encoder(b) Source encoder(c) Modulator(d) None of the mentionedI have been asked this question during an interview.The above asked question is from Digital Communication Signal Processing topic in section Signals and Spectra of Digital Communications
Answer» Correct choice is (b) Source encoder To EXPLAIN I would say: Source encoder converts the DIGITAL or ANALOG signal to a sequence of binary digits. This PROCESS is called as source encoding or COMPRESSION.
