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 ...
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 ...
Lock-in amplifiers let you measure very small signals that would otherwise get lost in the noise of even the best available amplifiers. Originally analog circuits, lock-in amplifiers have evolved into ...
