Transfer function Phase

    Given w =1, What is phiG ? Is it the phase difference between the two waves? If it is, isn't it simply phiG = (delta t/T)*360 but I am not getting the right answer.

    PhiG = (0.5/2pi)*360 = 28.6

    Also I don't know where this wt + phi = 2pi equation comes from.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    The period appears to be about 6.3 s

    The diagram is drawn wierdly. The waveforms appear to have a fixed phase difference everywhere except near t = 0 where one has been deliberately distorted to force it through the point (0,0). That origin region would be best ignored, it is so wrong.

    There is also a +/- sign associated with the phase difference, according to whether the system introduces a lead or lag, respectively.

    I think you should do a google search on: period and phase delay of sinewave
    as mastery of this fundamental material is crucial.
