Pulse With Modulation and Demodulation (PWM).
Experimental Training Board has been
designed to study on the modern techniques of pulse with modulation /
demodulation. Using this training board one can know the specialized
techniques of pulse with modulation and demodulation.
Practical experience on this board carries great educative value for science and engineering students.Object:
To modulate a pulse carrier with sinusoidal signal to obtain a pulse width modulated signal
To demodulate the pulse with modulated signal to obtain 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 Width Modulator based on timer
Pulse Width Demodulator based on operational amplifier
Adequate no. of other electronic components
