Differential Pulse Code Modulation(DPCM) Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12550

Indian Lab Suppliers supplies the Differential Pulse Code Modulation (DPCM) Trainer (Product ID: 12550), part of the Communication Equipment range under Laboratory equipment, a self-contained board built around practical telephone-network-style sampling and audio-processing frequencies, with an onboard DPCM transmitter and receiver.

Note on naming: this board's name is identical to another trainer in our range, so please confirm the exact model with our team. This board samples at 8 kHz with 5 bits per sample (including the sign bit), a telephone-network-style configuration that reduces bandwidth compared to standard 8-bit PCM by 3 bits per sample. This differs from our Differential Pulse Code Modulation and Demodulation Trainer (Product ID 12536, ADC-based design sampling at 2.5 kHz with 8-bit digital output).

Note on scope: for a sampler/quantizer/linear-predictor based DPCM design (16 kHz sampling), see our DPCM/ADPCM Modulation/Demodulation Trainer (Product ID 12585).

Quick Answer

This trainer lets students study DPCM transmission and reception built around practical public-telephone-network sampling and audio-processing frequencies, observing the audio input/output processing stages, control-signal flow (read/write, reset, latch enables, output enables) and the bandwidth saving of 5-bit DPCM samples compared to standard 8-bit PCM.

Key Features

Onboard DPCM transmitter and receiver · onboard signal generator block · onboard audio input processing circuit · onboard audio output processing circuit · clock and complete control-signal section · detailed signal-processing circuit with complete data and control-signal flow.

Frequently Asked Questions

How is this different from your other DPCM trainer?
This board uses an 8 kHz sampling rate with 5-bit samples in a telephone-network-style configuration, while our other Differential Pulse Code Modulation and Demodulation Trainer (Product ID 12536) uses an ADC-based design sampling at 2.5 kHz with 8-bit output. Please confirm with our team which platform best fits your curriculum requirement.

What bandwidth saving does DPCM offer here compared to PCM?
This trainer's 5-bit-per-sample DPCM scheme uses 3 fewer bits per sample than standard 8-bit PCM, reducing the bandwidth required to carry the same audio signal.

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.
