Product Description

 Frequency Modulation & Demodulation Trainer

Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of 

Object: To Study Theory of Frequency Modulation & Demodulation:

  • Frequency Modulation via varactor / reactance Modulation
  • Frequency Demodulation via Detuned Resonant / Ratio / Qudrature / Foster - Seeley / Phase locked loop detector
  • Separate VCO circuit to demonstrate FM waveform

Feature:

The board consists of the following built-in parts:

  • POWER SUPPLY : ± 12DC IC Regulated power supply
  • FM Modulating signal generator : Sine wave
