FPGA-Based Digital Lock-in Amplifier With High-Precision Automatic Frequency Tracking
Aiming to overcome the problem of the frequency error between the reference signal and the measured signal in an analog lock-in amplifier, this paper presented a digital lock-in amplifier (DLIA) with accurate frequency automatic tracking to improve its performance. In this paper, a modular design ap...
