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

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.
