SOLVED: In MultiSim, design a PWM circuit as described in the Background and Theory section. You will need a 0 to 9 counter, which you should build from flip flops and basic logic gates. The PWM input will come from 4 input switches as a binary number. For the comparator, you can build your own from basic gates, or use one of the commercially available comparator chips (74HC85 Digital IC). An oscilloscope in MultiSim can be used to verify duty cycles.PWM Controller DesignA common design for a PW
