I read the paper
http://www.designers-guide.org/Modeling/JTOL_rev1.0.pdfBut I really confused with
equation (1) for UDJ
Vudj/Vprbs7 = tanh(7Tck/2t)
and equation (6) for DDJ
DDJpp[UI] = (t/Tb)ln((1+exp(-Tmin/t)/(1+exp(-Tmax/t))))
The paper doesn't show where the equations come from. Can someone here tell me something about them? Thanks,
