Development of portable orthogonal lock-in amplifier based on FPGA
A portable orthogonal phase-locked amplifier for weak signal detection has been developed based on FPGA. First,the signal processing module receives the signal,does variable gain amplification on the signal and puts it through the power frequency noise filtering. The signal is put into the FPGA thro...
