Instructions Design the synchronous 3-bit binary down counter with D-lip-flops and any number of 2to1 multiplexers. Inverters can be used. The flip-flop outputs serve as outputs of the counter following the sequence 000-> 111-> 110-> 101->100->011->010->001- > ..and repeat from 000. The initial state is not critical. 1. Obtain the D-flip-flip input excitation equations 2. Implement the equations with any number of 2to1 multiplexers. Sketch the schematic.
