DSB and SSB-SC Amplitude Modulation and Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : JA-CT-1495
The DSB and SSB-SC amplitude modulation and demodulation trainer puts a complete AM system on a single 300 x 400 mm PCB. Students generate AM, DSB-SC and SSB-SC signals, measure the modulation index, and demodulate with a diode (envelope) detector, square-law detection and product detectors, using a built-in 300 Hz-3.4 kHz AF generator, a 100 kHz-1 MHz RF carrier oscillator and a microphone input (SKU JA-CT-1495).

Scope of supply and ordering
The listing covers the AM trainer board with its microphone, loudspeaker box and operating instructions, supplied by JaincoLab. Quantities, packing and delivery lead time are stated on each quotation.
Frequently asked questions
Which modulation types does the AM trainer cover?
Conventional AM, DSB-SC and SSB-SC, each with its demodulator.
Can voice be transmitted on the trainer?
Yes. A dynamic microphone and an input audio amplifier allow voice AM modulation and demodulation, heard on the loudspeaker box.
What carrier range is available?
An RF carrier oscillator from 100 kHz to 1 MHz with 0 to 10 Vpp output, plus a 400-500 kHz local oscillator.
