Product Code : SCL-CE-12541
Indian Lab Suppliers supplies the Advanced Frequency Modulation and Demodulation Trainer (Product ID: 12541), part of the Communication Equipment range under Laboratory equipment, a single-PCB (300 x 400 mm) training board covering FM generation via varactor and reactance modulation and demodulation via five different detector schemes, requiring an external oscilloscope.
Note on scope: this board offers five separate demodulator circuits (detuned resonant, quadrature, Foster-Seeley, ratio, and phase-locked loop) for direct comparison, distinct from our simpler, single-scheme Frequency Modulation and Demodulation Trainer (Product ID 12524, slope-detector based). Please confirm with our team which platform best fits your curriculum requirement. We also offer an even more elaborate Frequency Modulation/Demodulation Techniques Trainer (Product ID 12542) with three modulator circuits and six demodulator circuits.
Quick Answer
This trainer lets students study frequency modulation via varactor and reactance modulator circuits (each with carrier frequency adjustment), and compare five different FM demodulation techniques — detuned resonant, quadrature, Foster-Seeley, ratio, and phase-locked loop detectors — while also investigating the effect of noise on FM detection using an onboard VCO circuit and mixer/amplifier stage.
Key Features
