DPCM/ADPCM Modulation/Demdulation Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12585

Indian Lab Suppliers supplies the DPCM/ADPCM Modulation/Demodulation Trainer (Product ID: 12585), part of the Communication Equipment range under Laboratory equipment, a sampler-quantizer-linear-predictor based board for studying Differential Pulse Code Modulation encoding and decoding.

Note on scope and source data: the source specification for this trainer describes only DPCM (a sampler, quantizer and linear predictor for modulation; a linear predictor, integrator and low-pass filter for demodulation), with no adaptive-quantization detail to support the "ADPCM" portion of the product name — please confirm with our team whether adaptive quantization is included. The source feature list also included a "receiver clock generated by PLL, demodulation via PLL and envelope detector" line that is inconsistent with this board's documented sampler/quantizer/linear-predictor design (it appears to be a carried-over artifact from an unrelated listing) and has been omitted here; please verify the demodulation method with our team before ordering. Separately, this board's sampler/quantizer/linear-predictor architecture (16 kHz sampling clock, 64–512 kHz data clock) is a different design from our ADC-based Differential Pulse Code Modulation & Demodulation Trainer (Product ID 12536, 2.5 kHz sampling) and our telephone-network-style Differential Pulse Code Modulation (DPCM) Trainer (Product ID 12550, 8 kHz/5-bit sampling); please confirm the exact model with our team.

Quick Answer

This trainer lets students study DPCM modulation using a sampler, quantizer and linear predictor, and DPCM demodulation using a linear predictor, integrator and low-pass filter, with an onboard 500 Hz test sine-wave generator, a jumper-selectable data clock (64, 128, 256, 512 kHz) and a 16 kHz sampling clock.

Frequently Asked Questions

Does this trainer include adaptive quantization (ADPCM)?
The available specification documents standard DPCM using a sampler, quantizer and linear predictor, with no adaptive-quantization detail confirmed; please check with our team if ADPCM operation is required for your curriculum.

How is this different from your other DPCM trainers?
This trainer uses a sampler/quantizer/linear-predictor design with a 16 kHz sampling clock, which differs from our ADC-based Differential Pulse Code Modulation & Demodulation Trainer (Product ID 12536) and our telephone-network-style Differential Pulse Code Modulation (DPCM) Trainer (Product ID 12550); please confirm the exact model with our team.

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.
