Question: Design a disk spinning animation circuit for a CD player. The input to the circuit will be a 3-bit number A 1 A 2 A

Design a “disk spinning” animation circuit for a CD player. The input to the circuit will be a 3-bit number A1 A2 A3 provided by another circuit. It will count from 0 to 7 in binary, and then it will repeat. The animation will appear on the top four lights of the LED display, shown in the figure below, going clockwise. The animation should consist of a blank spot on a disk spinning around once. Then the entire disk should blink on and off twice. The pattern is shown in the figure.

Design your circuit using only NOR gates with not more than four inputs in each. Minimize the number of gates required.
