Analog Devices is aiming at low-power signal measurement with a combined synchronous demodulator and filter chip which allows precision magnitude and phase measurements to be made on analogue signals ...

Synchronous detection is a measurement method where a stimulus is modulated with some frequency and the response is demodulated to bring the signal back down to base band. Performed when a dc stimulus ...

The ADA2200 synchronous demodulator incorporates a configurable analog filter enabling precision magnitude and phase measurements on analog signals in the presence of large noise sources. With input ...

In the late 1970s, television de- modulators became available with synchronous detectors, providing a method of monitoring the in-phase and quadrature signal components of television transmitters.

The theoretical and practical requirements for introducing synchronous demodulation into domestic receivers for MF/LF broadcasting are discussed. The difficulties encountered in the construction and ...
