2019_Question D_Simple Circuit Characteristic Tester

I. Problem Requirements
II. Design Analysis
This design mainly consists of a DDS module, a voltage RMS detection circuit module, a multi-channel AD conversion module (AD7606), a microcontroller, and a serial port display module. The FPGA controls the DDS module to generate the input signal, and the ADC module collects the signal under test after processing by the preceding circuitry and sends it to the FPGA for processing. The FPGA analyzes the obtained data and sends the relevant data to the STM32 microcontroller via serial port for further processing. Finally, the STM32 controls the serial port display to show the required data and waveforms.
