Pulse With Modulation & Demodulation (PWM)

Model HV-EXP2208
Experimental Training Boardhas 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 apulse 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. Mains Adequate no. of patch cords stackable from rear both ends 2mm spring loaded plug length ½ metre Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestionsand Book References Weight :3Kg.
