Which of the following are examples of data encoding schemes?
A. Non-Return to Zero (NRZ)
B. Manchester Encoding
C. Amplitude Modulation
D. Hamming code
E. Bipolar AMI

Solution

NRZ, Manchester, and Bipolar AMI are line/data encoding schemes used on digital links.
Amplitude Modulation is a carrier modulation scheme (analog).
Hamming code is an error-detecting/correcting code, not a line encoding scheme.
