The lock-in amplifier is actually an analog Fourier transformer. The output of the lock-in amplifier is a DC voltage, which is proportional to the signal ...
The board arrived yesterday afternoon, thanks to ST and EEWORLD. Let me tell you my initial impression. First, I found that the MCU is STM32G431RB after I got the board. This MCU is the basic STM32G4X...
