Sine wave audio frequency: 1 KHz-10KHz/0-10VP-P  Approx

Carrier frequency : 90KHz/5.6V P-P Approx

Housed in ABS cabinet, circuit diagram printed, connections of
 arious components (IC 2206,IC 565 & IC 741), 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 using PLL circuit & observe change in the phase of carrier according the amplitude of the Modulating signal.
