Design of Periodic Signal Measurement and Analysis Device Based on Analog Preprocessing and FPGA Parallel Processing
Combining analog preprocessing with FPGA parallel signal analysis, this paper implements a device for time domain and frequency domain measurement of periodic signals. The system consists of amplifying circuits, a 7 order Butterworth low pass filter, a 14 bit ADC chip Zynq 7020 and a serial port screen, and adopts anal...
