Delta, Adaptive Delta and Delta Sigma Modulation / Demodulation Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12493

Indian Lab Suppliers supplies the Delta, Adaptive Delta and Delta Sigma Modulation / Demodulation Trainer (Product ID: 12493), part of the Communication Equipment range under Laboratory equipment, a trainer covering Delta Modulation, Adaptive Delta Modulation and Delta-Sigma Modulation and Demodulation with the transmitter and receiver built on the same board.

Note on naming and scope: our catalog also includes the Delta/Adaptive Delta Modulation/Demodulation Trainer (Product ID 12575); please confirm the exact model with our team. Both cover Delta and Adaptive Delta modulation, but this trainer uses a 6.4 MHz crystal with 50/100/200/400 kHz sampling and covers Delta-Sigma modulation, while Product ID 12575 uses an 8/16/32/64 kHz sampling clock with an onboard compander/expander and covers CVSD modulation instead of Delta-Sigma.

Quick Answer

In digital communication, especially at low frequencies or in speech communication, a saving in bandwidth can be achieved using Delta Modulation and its associated techniques, because each sample only needs single-bit encoding. This trainer covers Delta, Adaptive Delta and Delta-Sigma Modulation and Demodulation, with the transmitter and receiver on the same board, switch-selectable sampling rates, four synchronized on-board signal generators, selectable integrator gain settings, and an on-board 4th-order Butterworth low-pass filter with a unipolar-to-bipolar converter.

Note on naming: we also supply a similarly named Delta, Adaptive Delta, Sigma Delta Modulator & Demodulator (Product ID 12511), a distinct, more extensively equipped unit that adds first- and second-order Sigma-Delta modulation stages, a DDS-based internal generator with external signal input, and optional Simtel 11 software. Please confirm the exact model with our team if you are comparing the two.
