Frequency Shift Keying (FSK) Modulation & Demodulation.

Objective :

a) Observe Shift in Carrier Amplitude according to the Binary Input i.e. Digital Clock Signal.

b) Recovery of Modulating Signal from Demodulator Circuit using Phase Locked Loop following by a Low Pass Filter & Comparator

Technical Specification :

* In built IC based DC Regulated Power Supply ±12V/ 250mA

* On board Data Signal Generator, Frequency : 10KHz & 5KHz, Amplitude : 5Vpp Approx.

* On board Carrier Signal Generator, Frequency : 100KHz & 50KHz, Amplitude : 6Vpp Approx.

* Modulation using Linear Multiplier (Balanced Modulator using IC LM 1496) followed by adder TL081

* Demodulation using Phase Locked Loop using IC 4046 followed by Low Pass Filter TL082 & Comparator IC 3140

* Glass Epoxy PCB used as front panel & mounted on light weight shock proof plastic cabinet

Power Requirement : 220V AC ±10%, 50Hz

Standard Accessories : Patch Cords & Instruction Manual
