Pulse Position Modulation and Demodulation

Pulse Position Modulation & Demodulation  Object:- To modulate a pulse train (carrier) with a sinusoidal signal and to obtain a Pulse Position Modulated signal. To demodulate a Pulse Position Modulated signal to recover the modulating signal. Features:- The board consists of the following built in parts :- ± 6V D.C. at 100mA, IC regulated Power Supply internally connected Pulse Train (Carrier) Generator based on timer IC 50 Hz A.C. sinusoidal modulating signal obtained from stepped down transformer Pulse Position Modulating circuit based on IC Demodulating circuitry based on an IC and transistors Adequate no. of other electronic components Mains ON/OFF switch, Fuse and Jewel light The unit is operative on 230V ±10% at 50Hz A.C.
