Dual Dirac Estimation
If the jitter elements include DJ, the histogram has multiple peaks at the
waveform cross point. Dual Dirac Estimation is a method to estimate RJ
and DJ using Dual Dirac function as the fitting curve of this histogram.

The Dual Dirac distribution is expressed as the combined formula of two
normal distributions.
