Amplitude Modulation & Demodulation Trainer

Communication Trainers
Order Code 40501


Experimental Training Board has been designed specifically for the study of Amplitude Modulation and Demodulation. This training board is based on latest solid state circuits for generating modulating signal, Amplitude Modulation and Demodulation.
Practical experience on this board carries great educative value for Science and Engineering Students.

To study the process of Amplitude Modulation & Demodulation

01. To observe the carrier waveforms on C.R.O
02. To modulate carrier with audio signal and to observe waveforms on C.R.O
03. To measure percentage modulation of the amplitude modulated waveform
04. To demodulate amplitude modulated waveform and observe on C.R.O
