Hello,
I wanted to plot the phase of a transfer function. I was doing it like
this:
LogLinearPlot[Phase[w], {w, 0, wmax}]
Where Phase is calculated using the ArcTan function. The problem is tha=
t
the ArcTan function rounds up the result to positive values when the phase
goes below -pi. But I want the phase to keep going negative values upto
infinity. Is there a way to do this using some standard functions?
