SPECIFICATION

Experimental Training Board has been designed specifically for the study of Amplitude Modulation and demodulation with basic Diode detector. The Training Board is helpful for the study of improved Diode Detector and detection of efficiency of a diode in Amplitude Modulation and Demodulation.
Practical experience on this board carries great educative value for Science and Engineering students.

Object:
To study the Diode Detector.
01. To modulate the carrier with audio signal and measure modulation index.
02. To demodulate the amplitude modulated waveform by the basic diode detector.
03. To demodulate the amplitude modulated waveform by the improved diode detector.
04. To study the detection efficiency of a Diode by direct method.

Features:
The board consists of the following built-in parts:
01. 9V DC at 100mA, regulated Power Supply internally connected.
02. D.C. Milliammeter, 65mm rectangular dial to read 0-1mA.
