FPGA is the data processing core of the whole system. This system can produce two low-frequency signals at the same time, at the same time, the two signals can be superposed for spectrum analysis, and the amplitude and frequency can also be extracted, and the extracted information can be displayed through the liquid crystal module. The test results show that the system is simple, easy to implement, and stable. Has a vast application space.
