Abstract
The design takes STM32F103 processor as the core,carries embedded real-time operating system,and realizes the functions of oscilloscope,simple signal generator and electronic photo album.The pulse interference is effectively eliminated by filtering and interpolation algorithm,and the input signal is processed by attenuation,impedance transformation,program-con-trolled amplification,etc.Through the signal processing module,the accuracy and stability of the measured waveform parame-ters are realized.The test shows that the system has reliable operation,stable performance,high accuracy of waveform signal,and can meet the requirements of portability and low cost.
