Sin(x)/x
Connecting the sampling points with curves has stronger versatility. Sinx interpolation method uses
mathematical processing to calculate results in the actual sample interval. This method bending signal
waveform, and make it produce a more realistic regular shape than pure square wave and pulse. It is
recommended Sinx/s interpolation method be used when the sampling frequency is 3 to 5 times the
bandwidth frequency of the system.
