DPCM/ADPCM Modulation/Demodulation 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: the specification describes DPCM only (a sampler, quantizer and linear predictor for modulation; a linear predictor, integrator and low-pass filter for demodulation) and gives no adaptive-quantization detail for the "ADPCM" part of the product name. Please confirm with our team whether adaptive quantization is included and which demodulation method is used. This board's sampler/quantizer/linear-predictor design (16 kHz sampling clock, 64–512 kHz data clock) differs 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.
