(communications)
To recover the modulating wave from a modulated carrier. Also known as decode; detect.

demodulate

demodulate

To isolate a data signal from a carrier wave. The demodulation circuit uses the unmodulated carrier as a reference signal and compares it to the received signal. See modulation and carrier.

Given the benefits of wideband technology, WORK Microwave will be demonstrating its single carrier wideband modulator and demodulator at IBC2016.
After the optical transmission path, a modeling is going on by a demodulator block, in which the signal after passing through the optical path model is entering [12-15].
The single-channel Si218x demodulators use the same 7 mm x 7 mm QFN-48 package as Silicon Labs' previous demodulator family, providing pin-to-pin compatibility, simplifying board design, and minimizing cost and research and development.
The CapaNCDT 6200 can be expanded by simply adding a DL6220 demodulator, which provides an Ethernet interface, supporting fast and easy configuration through a web browser.
In this paper, the performances of an FPD and a TPD both connected to the baseband I/Q regeneration circuit discussed above are studied and compared to those obtained with a classical I/Q demodulator (IQD).
The CDD-564EN IP Demodulators receive four independent 70/140 MHz or L-Band channels and combine the output into a single 10/100Base-T Ethernet port for transmission onto the LAN.
Another time-alignment technique utilizes the sync-search functionality of the demodulators. This function searches through an incoming block of symbols until a predefined pattern is found and then begins demodulating at that point.
