TDM Pulse Code Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12574
Indian Lab Suppliers supplies the TDM Pulse Code Demodulation Trainer (Product ID: 12574), part of the Communication Equipment range under Laboratory equipment, a two-channel TDM-PCM receiver trainer with selectable error detection and Hamming-code error correction.
Note on naming and scope: our catalog also includes the TDM Pulse Code Modulation Receiver Trainer (Product ID 12492, which pairs with our TDM Pulse Code Modulation and Transmitter Trainer, Product ID 12491, to form a complete link); please confirm the exact model with our team. Both 12492 and this trainer are two-channel TDM-PCM receivers with PLL clock regeneration and Off/Odd/Even parity plus Hamming-code error detection and correction, but the documented operating speeds differ — this trainer is documented at Fast (approx. 240 kHz/channel) and Slow (approx. 1 Hz/channel), while Product ID 12492 is documented at Fast (320 kHz/channel) and Slow (1.9 Hz/channel) — and this trainer additionally documents two 4th-order Butterworth low-pass filters (3.4 kHz cutoff) and four switched faults for fault selection. We have not confirmed whether this trainer is intended to pair with our separate TDM Pulse Code Modulation Trainer (Product ID 12573); please verify before ordering as a set.
Quick Answer
This trainer accepts a two-channel time-division-multiplexed PCM input and demonstrates its demodulation, with a selectable fast (approx. 240 kHz/channel) or slow (approx. 1 Hz/channel) mode of operation, a pseudo-random sync code generator for frame synchronization, PLL-based receiver clock generation, selectable None/Even/Odd/Hamming error detection with Hamming-code error correction, and two 4th-order Butterworth low-pass filters (3.4 kHz cutoff) for channel reconstruction.

Frequently Asked Questions
How is this different from your TDM Pulse Code Modulation Receiver Trainer?
Both are two-channel TDM-PCM receivers with the same error-detection and correction scheme, but the documented operating speeds and filter/fault details differ; please confirm the exact model with our team. See our TDM Pulse Code Modulation Receiver Trainer (Product ID 12492) for the alternative model, which pairs with our TDM Pulse Code Modulation and Transmitter Trainer (Product ID 12491).
What error detection and correction does this trainer support?
Selectable None, Even, Odd or Hamming parity error detection, with error correction performed using the Hamming code technique.
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.
