Equation size = 1024
clock = 1e9
'pulse width
k0 = 20e-9
'peak location k1 = 512e-9
lorentz.wfm" = 1 / (1+(2*(time - k1) / k0) ^ 2)

Equation size = 2048
clock = 1e9
'sine frequency
k0 = 50e6
'peak location k1 = 1024e-9
sinc.wfm" = sinc(2 * pi * k0 * (time - k1))

This is the impulse response for the ideal low pass filter for the
frequency bandwidth f. At least 42 periods are required to use a
vertical resolution of 8 bits.
