Design a “disk spinning” animation circuit for a CD player. Theinput to the circuit will be a 3-bit binary number A1, A2, A3provided by 3-bit up counter. The circuit for 3-bit counter hasalready been provided in CCT file on Google Classroom, so there isno need to design the up counter yourself.
The animation will appear on the top four lights of the LED displayof Figure, i.e., on X1, X2, X7, and X6, going clockwise as shown inFigure 1.
Figure 1 Seven Segment Indicator
The animation should consist of a blank spot on a disk spinningaround once, beginning with X1. Then, the entire disk should blinkon and off twice. The pattern is shown in figure 2.

You have to design a circuit that must use two 2x1 multiplexers,and two 4x1 multiplexers in the design. You may also use logicgate(s) in the design.
(a) Draw the truth table for the circuit below. The truth tablemust cover all the possible cases. Stick to the notations use inthe question.

(b) Drive the input equations for the multiplexers.  

(c) Implement the same circuit on LogicWorks. The output of thecircuit must be shown through 7Seg Disp component in theLogicWorks. There is no restriction on the selection of 2x1 mux and4x1 mux variants available in the LogicWorks. You have to connectthe up-counter circuit already provided to you with your designedcircuit
