摘要
通过对输入信号的正弦插值处理 ,分析了输出信号的均方差 ,说明了正弦插值对信号处理的作用 。
The article introduces the application of sine interpolation algorithm to digital oscillograph.Through the interpolation processing for input signal,it analyzes the mean square error of output signal and explains the effect of interpolation on the signal processing.It gives a method to reduce the distortion of the sampling signal.
