Constants k0 indicates the half width (W50) for the pulse; k1 indicates the peak location
of the pulse.
Description The waveform generated when the pulse width is taken to be tW50 and the
peak location is taken to be 0 can be expressed as
Gaussian form in the frequency domain as well.
<Example> When t
w50
is 1 ms, the bandwidth will be 31.2 kHz.
