Differential Pulse Code Modulation & Demodulation Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12536

Indian Lab Suppliers supplies the Differential Pulse Code Modulation (DPCM) Trainer (Product ID: 12536), part of the Communication Equipment range under Laboratory equipment, a self-contained training board for the study of basic DPCM encoding and decoding, requiring a dual-trace external oscilloscope.

Note on scope: this board studies basic, standalone Differential Pulse Code Modulation, and is offered alongside our related PCM Trainer (Product ID 12534). For DPCM alongside PCM and CVSD on a single combined platform, see our PCM, DPCM, CVSD Modulator and Demodulator. Please confirm with our team which platform best fits your curriculum requirement. Note also our separate Differential Pulse Code Modulation (DPCM) Trainer (Product ID 12550), an identically-named but functionally different board built for telephone-network-style 8 kHz/5-bit sampling.

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 Differential Pulse Code Modulation and Demodulation: the DPCM modulator converts a baseband analog signal into 8-bit digital format via an ADC at a 2.5 kHz sampling rate, while the DPCM demodulator reconstructs the parallel data, converts it back to analog via a DAC, and recovers the original signal with a low-pass filter.

Key Features

Audio frequency oscillator, 10 Hz to 100 Hz, for the modulating signal · onboard DPCM modulator (encoder) · onboard DPCM demodulator (decoder) · 5V DC at 100 mA and ±12V DC at 100 mA, IC-regulated internal power supplies, plus a −5V to 5V variable DC output · mains ON/OFF switch, fuse and jewel light · 4 mm spring-loaded stackable patch cords, half-metre length · terminals/sockets on the panel for connections and waveform observation · detailed operating instructions covering object, theory, design procedure, report suggestions and book references.
