Frequency Modulation & Demodulation

Specification

Frequency Modulation & Demodulation

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:

• To observe the effect of D.C. voltage on frequency of carrier waveform
• To frequency modulate the carrier with Audio signal, observe F.M. waveform on C.R.O., and measure its modulation index
• To demodulate the F.M. singal and observe the output on C.R.O.
• To plot the characteristics curve of the slope detector demodulating circuit

Features:

The board consists of the following built in parts:

• ± 12V D.C. at 100 mA, IC Regulated Power Supply
• Carrier generator circuit which generates the carrier signal
• Audio frequency modulating signal
• Variable D.C. is provided to see the frequency deviation in carrier frequency
• Frequency Modulation circuit with buffer stage at the output
