Reference: Scientech2208 - Manufacturer: SCIENTECH TECHNOLOGIES

Scientech2208 Laboratory for Armstrong Frequency Modulator & Demodulator is a self contained Analog Communication board which provides an in-depth study of basic Armstrong method of Frequency Modulation.

It consists of an FM modulator which uses Armstrong method of Frequency modulation with the help of a DSB-SC Balanced Modulator, Carrier wave phase shifter and a Operational Amplifier based adder. Also a Demodulator section which demodulate the FM wave with PLL detector and a filter followed by an amplifier. Three different experiments show how FM wave generated using AM wave and then demodulated to extract the original modulating wave.

Product Features:

A self contained platform

Functional blocks indicated on board mimic

Input - Output and Test points provided onboard

Built in DC Power Supply

On board audio oscillator, carrier oscillator, modulator, phase shifter, amplitude adjusts & filter circuits

Compact size

Balanced modulator which allows audio input signal to be amplitude modulated (DSB-SC) by carrier input prior to frequency modulation, with balance adjustment
