Electrical Engineering

Implement the synchronous 2-bit Up/Down counter with saturationat the end states. The flip-flop outputs Q1, Q0 serve as theoutputs of the counter. The counting direction is set with modecontrol input M. With M =1 the flip-flop outputs follow theincrementing binary sequence starting from a current state withsaturation at state 11 as shown in the following example: 00->01-> 10-> 11-> 11-> 11... With M =0 the outputs followthe decrementing binary sequence from a current state withsaturation in state 00 as illustrated below: 11-> 10->01->00->00->00... Obtain the state table, the flip-flopinput excitation equations and implement them with any number of2-to-1 multiplexers. Inverters can be used. Obtain the counterschematic.
