Sinx/x
Use sine(x)/x interpolation
x
Use linear interpolation
Interpolation method is a processing method to connect the sampled points,
using some points to calculate the whole appearance of the waveform. Select
the appropriate interpolation method according to the actual signal.
Sine(x)/x interpolation
: Connect the sampled points with curved lines.
Linear interpolation
: Connect the sampled points with straight lines.
This
method is suitable to rebuild the straight-edged signals, such as square or
pulse wave.
