1. Provide diagrams of the NRZ-I, Manchester, and bipolar-AMI encodings for the following bit stream:
2. How many samples per second are required to digitize the following signals to avoid aliasing in the reconstructed signal:
a. Signal bandwidth less than 30,000 Hz
b. Signal bandwidth less than 1 MHz
c. Signal bandwidth less than 64 kHz
In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which "1s" are represented by one significant condition (usually a positive voltage) and "0s" are represented by some other significant condition (usually a negative voltage), with no other neutral or rest condition.

In telecommunication, Manchester code (also known as Phase Encoding, or PE) is a line code in which the encoding of each data bit has at least one transition and occupies ...
Signal encoding is examined. Diagrams for NRZ-I, Manchester and bipolar-AMI encoding is provided for a bit stream. The amount of samples per second which are required to digitize signals to avoid aliasing in the reconstructed signal is given.
