For a digitaly PWM modulator the maxium dutycycle may not be more than about 50% of the switching time. How can i simle made this with a LM393 comparator.
Here i have only one of the the comparators in use.
Or with the use with a Nand gate 4093.
The PWM signal is used in a PWM audio-modulator what modulate a AM transmitter.
