Product Code : SCL-CE-12584
Indian Lab Suppliers supplies the QAM/DQAM Demodulation Trainer (Product ID: 12584), part of the Communication Equipment range under Laboratory equipment, a dedicated demodulation-side trainer for recovering QAM and DQAM carrier signals using PLL and envelope-detector demodulation.
Note on pairing: this trainer is the demodulation (receiver) counterpart to our QAM/DQAM Modulation Trainer (Product ID 12583), which covers the modulation (encoder) side of QAM and DQAM with Tribit encoding; together the two demonstrate a complete QAM/DQAM modulation-demodulation link. Please confirm with our team whether you need this trainer alone or as a matched pair with Product ID 12583.
Quick Answer
This trainer lets students study QAM and DQAM carrier demodulation using PLL and envelope-detector demodulation, decoding Tribit (I, Q & C) data back to NRZ-L format with differential decoding of the I and Q bits, regenerating the receiver clock using a PLL method, and using switch-selectable faults to study circuit-fault effects.
Key Features

Frequently Asked Questions
Does this trainer need to be bought with the QAM/DQAM Modulation Trainer?
Not necessarily, but the two form a matched encoder/decoder pair; please confirm with our team whether you need this trainer alone or together with our QAM/DQAM Modulation Trainer (Product ID 12583) to demonstrate a complete link.
How is QAM/DQAM demodulated on this trainer?
The trainer uses a combination of PLL (phase-locked loop) and envelope-detector methods to recover the carrier and demodulate the Tribit-encoded I, Q and C data back to NRZ-L format.
