A Portable Analog Lock-In Amplifier for Accurate Phase
http://www.chem.ucla.edu/~craigim/pdfmanuals/appnotes/tn1003 A lock-in amplifier is a type of amplifier that can extract a signal with a known carrier wave from an extremely noisy environment. Depending on the dynamic reserve of the instrument, signals up to a million times smaller than noise components, potentially fairly close by in frequency, can still … Zobacz więcej The operation of a lock-in amplifier relies on the orthogonality of sinusoidal functions. Specifically, when a sinusoidal function of frequency f1 is multiplied by another sinusoidal function of frequency f2 not equal to f1 and Zobacz więcej Signal recovery takes advantage of the fact that noise is often spread over a much wider range of frequencies than the signal. In the simplest case of white noise, even if the Zobacz więcej • About LIAs from Stanford Research Systems.
