Phaser to Cartesian

  1. Mar 24, 2009 #1
    When converting an AC waveform (from polar) to a rectangular form, a source quotes v(t) as x + jy.

    But how is this possible?...I mean v(t) is clearly the x axis length of r (vm).

    Further more how does complex number come into the picture?...every thing is real.

    Is my source wrong?

    Are you not getting the question?

    in a polar form, you'll have the magnitude and a phase where a phase is nothing but actan(imaginary/real).

    thus in rectangular form indeed, you you'll have v(t) = x +jy wheer x = cos(phase) and y = sin(phase).

    Ok so one of the axes will return a wrong value...right?

    So how come v(t) = y + jx?; I mean it should be v(t) = y...the jx doesn't make a difference?
