1.	In channel encoding procedure(a) Redundancy bits are added(b) Errors are corrected(c) Redundancy bits are added & Errors are corrected(d) None of the mentionedThis question was addressed to me in an interview.Enquiry is from Modulation and Multiplexing in section Modulation and Coding Trade-off of Digital Communications
Answer» RIGHT answer is (C) Redundancy BITS are added & Errors are corrected The explanation is: In channel encoding includes addition of redundancy to the SIGNAL such that any BIT errors can be corrected.
