Data Communication and Signal Encoding Quiz

The three techniques involved in digital-to-digital conversion are line coding, block coding, and scrambling.

The purpose of line coding is to convert a string of 1’s and 0’s (digital data) into a sequence of signals that denote the 1’s and 0’s.

Data rate defines the number of data elements (bits) sent in 1 sec, while signal rate is the number of signal elements sent in 1 sec. The data rate is sometimes called the bit rate; the signal rate is sometimes called the pulse rate, the modulation rate, or the baud rate.
