Pulse Position Modulation Applications. Due to constant amplitude property it gets less affected by noise. Pulse modulation methods are used to transfer a narrowband analog signal such as a phone call over a pulse stream.
Advantages of pulse position modulation. These set and reset signals generate a pwm signal at the output of the flip flop. In this system the draining of water acts as the timing device and torches are used to signal the pulses.
Due to constant amplitude property it gets less affected by noise.
Similar to pwm ppm also shows better noise immunity as compared to pam. That used the water clock principle to time signals. 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.
