Bode stability criterion: Clearing a common misconception

Web4 Bode and Nyquist plots In brief, Bode (rhymes with roadie) plots show the the frequency response of a system. There are two Bode plots one for gain (or magnitude) and one for phase. The amplitude response curves given above are examples of the Bode gain plot. The Nyquist plot combines gain and phase into one plot in the complex plane.
