Product Code : SCL-CE-12515
Indian Lab Suppliers supplies the PCM, DPCM, CVSD Modulator and Demodulator (Product ID: 12515), part of the Communication Equipment range under Laboratory equipment, an extensive hands-on trainer covering Pulse Code Modulation, Differential Pulse Code Modulation and Continuous Variable Slope Delta Modulation, with the modulator and demodulator built on the same board, part of our broader Digital Communication Trainer family (Product ID 12489).
Quick Answer
This trainer provides hands-on study of PCM, DPCM and CVSD modulation and demodulation, including parallel-to-serial and serial-to-parallel conversion at varying line-speed clocks, DPCM predictor (differentiator) output, CVSD step-size generation, an on-board transmission-effect stage (attenuation, filtering and noise), and a 2nd-order Butterworth low-pass filter at each demodulator output, using an on-board DDS signal generator.
Key Features
Modulator and demodulator on the same board · on-board DDS signal generator for standard and arbitrary signals · selectable sampling frequencies with respective line speed · on-board transmission-effect stage · on-board 2nd-order Butterworth low-pass filter · SMD LED indicators · compact, book-like form factor for hands-on learning.
