Pulse With Modulation & Demodulation (PWM) For Electrical Lab Training

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 Mains ON/OFF switch, Fuse and Jewel light The unit is operative on 230V ±10% at 50Hz A.C.
