Sequential Logic: Many serial communication protocols, such as USB, use a signaling protocol known as non return to zero, inverted (NRZI) in which a 0 is represented as a transition and a 1 as no transition. Below is an example of a normal bit stream (NRZ) and how it would be encoded in NRZI as a waveform on the left and the corresponding bit streams on the right.

Draw a Mealy bubble-and-arc diagram for an NRZ-to-NRZI protocol converter.
