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 ...
Prepped for synchronous laser-beam detection applications such as print-start timers, the S9684 and S9684-01 photo ICs report highly stable digital outputs even when laser power or ambient temperature ...
Synchronous Detection is a useful technique for extracting low level signals buried below the noise floor, with many instrumentation applications. Some examples include measuring very small resistance ...
