5 Questions
Explain the three techniques involved in digital-to-digital conversion.
The three techniques involved in digital-to-digital conversion are line coding, block coding, and scrambling.
What is the purpose of line coding in data communication?
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.
Differentiate between data rate and signal rate in digital transmission.
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.
When is block coding and scrambling needed in digital-to-digital conversion?
Line coding is always needed; block coding and scrambling may or may not be needed.
What are the units of measurement for data rate and signal rate in digital transmission?
The unit of measurement for data rate is bits per second (bps), while the unit for signal rate is the baud.
