Description: Lock-in amplifier is a common method using correlation techniques extracting weak signals the noise in. It can be shown when the frequency and phase of the signal is known, the use of correlation detection technology enables maximum output signal to noise ratio. Digital lock-in amplifier than analog lock-in amplifier with a stable, high precision, and a digital filter passband can be set very narrow, in order to filter out noise.
