Accurately measuring the amplitude of a sinusoidal signal is a design challenge that is common to many data acquisition designs. The most famous and ubiquitous solution to this problem is synchronous ...

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 ...
