design 4 bit four way traffic light signal by using j k flip flop and 555 timer ic state equation and k map and also schematic diagram.

Solutions

Expert Solution

555 Timer is used to generate the clock signals for the flip-flops.

Traffic light control is shown below.

Thus, state diagram for the counter will be as follows:

Excitation Table of Counter

Expression for the Excitations can be derived using K-Map

Circuit
