摘要:According to the technical index of the filter,the parameters of the filter components are determined by theoretical calculation.The active low-pass filter is built on the NI ELVISⅡelectronic experimental platform.The signal is collected by the LabVIEW writing program.The time domain characteristics,the frequency characteristics and step response of the low-pass filter are analyzed by three methods.Finally,the effects of the Butterworth filter and the Bessel filter are compared and analyzed.The whole experimental process is simple and intuitive,and can better meet the needs of scientific research and teaching.
