Product Code : SCL-CE-12575
Indian Lab Suppliers supplies the Delta/Adaptive Delta Modulation/Demodulation Trainer (Product ID: 12575), part of the Communication Equipment range under Laboratory equipment, a trainer covering Delta and Adaptive/CVSD modulation and demodulation with onboard compander/expander and a unipolar-to-bipolar integrator.
Note on naming and scope: our catalog also includes the Delta, Adaptive Delta and Delta Sigma Modulation / Demodulation Trainer (Product ID 12493) and the Delta, Adaptive Delta, Sigma Delta Modulator & Demodulator (Product ID 12511); please confirm the exact model with our team. All three cover Delta and Adaptive Delta modulation, but the documented hardware differs: this trainer uses a switch-selectable 8/16/32/64 kHz sampling clock with an onboard compander/expander, CVSD modulator/demodulator, and both 2nd- and 4th-order Butterworth filters; Product ID 12493 uses a 6.4 MHz crystal with 50/100/200/400 kHz sampling and covers Delta-Sigma modulation instead of CVSD; Product ID 12511 is a comprehensive DDS-based platform covering Delta-Sigma (first and second order) with an internal/external signal generator and 46 test points. We also supply a simpler Delta Modulation & Demodulation Trainer (Product ID 12531) covering Delta modulation only.
Quick Answer
This trainer lets students study Delta Modulation and Adaptive/CVSD Modulation and demodulation, using an onboard sine wave generator (250 Hz, 500 Hz, 1 kHz, 2 kHz), a switch-selectable crystal-controlled sampling clock (8 kHz, 16 kHz, 32 kHz, 64 kHz), a unipolar-to-bipolar integrator, onboard compander and expander, and 2nd- and 4th-order Butterworth low-pass filters (3.4 kHz cutoff) for demodulated-signal reconstruction.

Frequently Asked Questions
How is this different from your other Delta/Adaptive Delta trainers?
This trainer uses CVSD modulation with a compander/expander and 8–64 kHz sampling; please confirm the exact model with our team. See our Delta, Adaptive Delta and Delta Sigma Modulation / Demodulation Trainer (Product ID 12493) and our Delta, Adaptive Delta, Sigma Delta Modulator & Demodulator (Product ID 12511) for the Delta-Sigma-based alternatives, or our Delta Modulation & Demodulation Trainer (Product ID 12531) for a Delta-only trainer.
What is CVSD modulation used for on this trainer?
Continuously Variable Slope Delta (CVSD) modulation and demodulation is demonstrated onboard alongside standard Delta modulation, with a unipolar-to-bipolar integrator and Butterworth filtering for signal reconstruction.
