    Hi there,

    What are you trying to do, work out the Nyquist Criterion?

    The Nyquist plot is a diagram of the phase and gain versus frequency of a system plotted on one line. It shows the phase as the angle and the magnitude as the distance from the origin of the plot. You measure or calculate the phase and gain of the circuit or system and then generate the plot. Here is a discussion of how to draw them.

    So what is your question about this process?
