Homework Help: Complex signal in polar form

  1. May 16, 2008 #1
    Hi I found this problem in the Fundamentals of Signals and Systems by Boulet problem 1.1

    find the polar form of following signal.

    x(t) = t / ( 1 + it)

    I know Amplitude = |t| / ([tex]\sqrt{[/tex](1 + t[tex]^{2}[/tex])}

    now how do we find the phase. Any help is appreciated.

    If you write the function in "a + ib" form, phase is easier to calculate.
