Abstract :
Digital storage oscilloscope can only acquire a small number of sampling points when it works in high-speed, in order to resume the waveform perfectly, we must interpolate some points between the sampling points (waveform reconstruction). The paper describes the basic sine interpolation algorithm, window function is introduced based on the actual application of the sine interpolation, and a computer simulation waveform is presented.
