A lock-in amplifier is a type of amplifier that can extract a signal with a known carrier wave from an extremely noisy environment. The device is often used to measure phase shift, even when the signals are large, have a high SNR, and do not need further improvement.
The digital lock-in amplifier has a wide range of applications.
