Frequency Modulation & Demodulation

SPECIFICATIONS:

Output voltage (Regulated): : ±12V DC (Inbuilt)

 Sine wave audio frequency : 2KHz & 4KHz/0-2.8VP-P Approx.

Carrier frequency : 62KHz/5.5V P-P Approx.

Housed in ABS cabinet, circuit diagram printed, connections of various components (IC LM 565, IC 8038), all important outputs & test points brought at Glass Epoxy (PCB) front panel. Also provided with power chord, patch chords & instruction manual.

Recovery of modulated signal from demodulator circuit, observe change in the carrier frequency according to the amplitude of the modulating signal & calculate modulation index
