# Is it standard practice to use degrees to represent the phase in frequency response analysis?

From MurrayWiki

It usually is standard practice to use degrees to represent the phase or phase margin, although you can certainly use radians (use the formula Phase = 2*pi*(deltaT/T) or Phase = 360*(deltaT/T), as long as you are consistent. For example, in electronic amplifiers, phase margin is the difference, measured in degrees, between the phase angle of the amplifier's output signal and -360° (wikipedia). --Soto 18:36, 22 October 2007 (PDT)
