1.	The method using which the error propagation in dubinary signalling can be avoided is(a) Filtering(b) Precoding(c) Postcoding(d) None of the mentionedI got this question in an interview for job.This is a very interesting question from Correlative Coding topic in division Formatting and Baseband Modulation of Digital Communications
Answer» RIGHT option is (b) Precoding The explanation is: In DUOBINARY SIGNALLING method if one error OCCURS it REPEATS everywhere through out the next steps. To avoid this precoding method can be used.
