Product Code : SCL-CE-12538
Indian Lab Suppliers supplies the DSB/SSB Amplitude Modulation and Demodulation Trainer (Product ID: 12538), part of the Communication Equipment range under Laboratory equipment, a single-PCB (300 x 400 mm) training board covering standard AM, DSB-SC and SSB-SC amplitude modulation and demodulation, with onboard microphone and speaker for live voice communication, requiring an external oscilloscope.
Note on scope: this board covers standard AM plus DSB-SC and SSB-SC suppressed-carrier variants with a local-oscillator/bandpass-filter scheme, distinct from our simpler DSB-AM Modulation and Demodulation Trainer (Product ID 12509) and our classic-era Amplitude Modulation and Demodulation Trainer (Product ID 12523). Please confirm with our team which platform best fits your curriculum requirement.
Quick Answer
This trainer lets students study standard Amplitude Modulation and Demodulation, Double Sideband Suppressed Carrier (DSB-SC) modulation and demodulation via a product detector, and Single Sideband Suppressed Carrier (SSB-SC) modulation and demodulation via a product detector using a local oscillator and bandpass filter, including live voice AM modulation and demodulation using an onboard microphone and speaker.

Frequently Asked Questions
Does this trainer include the oscilloscope needed for the experiments?
No, a 20 MHz cathode ray oscilloscope is required as separate apparatus and is not included with this board.
Can this trainer demodulate live voice, not just a signal generator input?
Yes, an onboard dynamic microphone and loudspeaker let students perform live voice AM modulation and demodulation in addition to the signal-generator-based experiments.
Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
