Finding A Transfer function:

  1. Oct 23, 2012 #1
    1. The problem statement, all variables and given/known data
    For my particular circuit I have found my transfer function already, which comes out to be:

    H(jω)= R / [R+(1/jωC)+jωL]

    I am now supposed to express it in polar form. I am confused on how I express such an expression in polar form. Could anyone give me some information on how to convert a transfer function to its polar form?

    2. Relevant equations
    None

    3. The attempt at a solution
    I have no solution for now as I am not sure on how to express an equation in polar form. The only thing I can think of is to replace the jω to change it to the s domain, but is this really polar form? I am confused, any help would be appreciated!

    Polar form consists of a magnitude and an angle...

    Your transfer function is a complex number that is a function of frequency (w). Polar form represents a complex number as a magnitude and phase.
