Frequency Modulation & Demodulation For Electrical Lab Training Description and Specifications for Lab Tenders
Frequency Modulation and 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
Demodulating circuit
