Pulse Position Modulation Applications. The pwm signal is applied to pin no 2 through the diode r 1 c 1 combination. Three main variants of pulse modulation are.
These set and reset signals generate a pwm signal at the output of the flip flop. This reference pulse is used to set the flip flop. Pulse position modulation ppm is a form of signal modulation in which m message bits are encoded by transmitting a single pulse in one of possible required time shifts.
Indication of sample amplitude is infinitely variable.
This pwm signal is then further processed in order to provide the original message signal. In pulse modulation continuous signals are sampled at regular intervals. Thus during signal transmission the signal undergoes pulse width modulation. Indication of sample amplitude is infinitely variable.
