Product Code : SCL-CE-12534
Indian Lab Suppliers supplies the Pulse Code Modulation (PCM) Trainer (Product ID: 12534), part of the Communication Equipment range under Laboratory equipment, a self-contained training board for the study of basic PCM encoding and decoding, requiring an external oscilloscope.
Note on scope: this board studies basic, standalone Pulse Code Modulation. For PCM alongside DPCM 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.
Quick Answer
This trainer lets students study Pulse Code Modulation and Demodulation: the PCM modulator converts a baseband analog signal into 8-bit digital format via an ADC at a 2.5 kHz sampling rate, serializing it into a 33 kbps bit stream, while the PCM 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
