Amplitude Shift Keying (ASK) Modulation & Demodulation

Objective :

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

b) Recovery of Data Signal from Demodulator Circuit

Technical Specification :

* In built IC based DC Regulated Power Supply ±12V, +5/ 250mA

* On board Data Signal Generator, Frequency 5KHz, Amplitude : 4Vpp Approx.

* On board Carrier Signal Generator, Frequency : 100KHz, Amplitude : 5Vpp Approx.

* Modulation using Linear Multiplier (Balanced Modulator using IC LM 1496).

* Demodulation of Diode as Envelop Detector, Low Pass Filter using IC TL 082 followed by Comparator IC using LM 311.
