Frequency Modulation and Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : JA-CT-1496
The frequency modulation and demodulation trainer is an FM transmitter and receiver on a single 300 x 400 mm PCB. It generates FM with varactor and reactance modulators and demodulates it with detuned resonant, quadrature, Foster-Seeley, ratio and phase-locked loop detectors, with a separate VCO circuit, a noise mixer, 8 switched faults and 78 test points (SKU JA-CT-1496).

Frequently asked questions
Which FM detectors can be compared?
Detuned resonant, quadrature, Foster-Seeley, ratio and phase-locked loop detectors.
How is noise introduced?
A mixer/amplifier with gain adjustment lets the FM signal be amplitude modulated by a noise input before demodulation.
How many switched faults are there?
Eight on-board switched faults, with 78 test points.
