Design of a Portable Multifunctional Signal Modulation Measurement System Based on STM32
摘要
Abstract
This paper designs and produces a portable multifunctional signal modulation measurement system based on STM32,uses STM32F103 as the main control chip,and achieves automatic discrimination of modulation modes by processing the previous signal conditioning circuit.A dedicated hardware demodulation module has been designed to conduct the signal modulation for the modulated signal,and the demodulation waveform is presented intuitively.In order to facilitate the measurement of amplitude modulation by single-chip microcomputer,an effective value detection circuit and an ADC voltage acquisition module are designed to convert analog signals and achieve measurement of amplitude modulation.It uses FPGA and other precision measurement methods to measure signal frequency modulation,achieves data transmission and display through communication between FPGA and single-chip microcomputer,and utilizes wireless modules and cloud platforms to achieve remote display and control of data.关键词
