Question:

Repeat Problem 4-23, designing a sequential circuit that transforms an NRZI message into a normal message. The mapping for such a circuit is as follows:

(a) If a change from 0 to 1 or from 1 to 0 occurs between adjacent bits in the NRZI message, then the message bit is a 0.

(b) If no change occurs between adjacent bits in the NRZI message, then the message bit is a 1.

Problem 4-23:

In many communication and networking systems, the signal transmitted on the communication line uses a non- return- to- zero (NRZ) format. USB uses a speciic version referred to as non- return- to- zero inverted (NRZI). A circuit that converts any message sequence of 0s and 1s to a sequence in the NRZI format is to be designed. The mapping for such a circuit is as follows:
