Pulse Amplitude Modulation and Demodulation (PAM)

SKU: Pulse Amplitude Modulation and Demodulation (PAM) 40503

Communication trainers


Product Description:

Experimental Training Board has been designed specifically for the study of Pulse Amplitude Modulation & Demodulation. Using this training board one can know the specialized techniques of Pulse Amplitude Modulation and Demodulation.

Practical experience on this board carries great educative value for Science and Engineering Students.



• To demonstrate sampling of a sine wave audio signal thereby converting it into Pulse Amplitude Modulated Signal (PAM).

• To demonstrate demodulation of PAM signal thereby recovering the sine wave audio signal.

• To demonstrate the effect of sampling-rate on the distortion in recovered ine wave audio signal.



The board consists of the following built-in parts:

• ±9V D.C. at 100mA, IC regulated Power Supply internally connected

• Variable frequency sampling pulse generator

• Sine wave audio frequency modulating signal generator

• PAM Modulator circuit based on an operational amplifier

• PAM Demodulator circuit based on a point contact diode and an 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 Suggestions and Book References

• Weight : 3 Kg. (Approx.)

• Dimension : W 340 x H 110 x D 210


Other Apparatus Required:

• Cathode Ray Oscilloscope 20MHz
