Frequency Modulation (FM) & Demodulation Trainer

The experimental Training Board has been designed specifically for the study of Frequency Modulation and Demodulation.

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

Object:

01. To observe the effect of D.C. voltage on the frequency of carrier waveform

02. To frequency modulate the carrier with Audio signal, observe F.M. waveform on C.R.O., and measure its modulation index

03. To demodulate the F.M. signal and observe the output on C.R.O.

04. To plot the characteristics curve of the slope detector demodulating circuit

Features:

The board consists of the following built-in parts:

01. ± 12V D.C. at 100 mA, IC Regulated Power Supply

02. Carrier generator circuit which generates the carrier signal

03. Audio frequency modulating signal

04. Variable D.C. is provided to see the frequency deviation in carrier frequency

05. Frequency Modulation circuit with buffer stage at the output

06. Demodulating circuit

07. Adequate no. of other electronic components

08. Mains ON/OFF switch, Fuse and Jewel light

The unit is operative on 230V ±10% at 50Hz A.C. Mains
