Frequency Modulation & Demodulation

SKU: Frequency Modulation & Demodulation 40502

Communication Trainers

Product Description:

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.



• 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



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

• Adequate no. of other electronic components

• Mains ON/OFF switch, Fuse and Jewel light

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

• Adequate no. of patch cords stackable from rear both ends 4mm spring loaded plug length ½ metre

• Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections & observation of waveforms

• Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References

• Weight : 3 Kg. (Approx.)

• Dimension : W 340 x H 110 x D 210


Other Apparatus Required:

• Decade Audio Frequency Generator Order Code - 16903

• Digital Frequency Counter, 6 digit Order Code - 16904

• Cathode Ray Oscilloscope 20MHz
