I have this transfer function: $$H(x)= \frac{1}{x+i(1+x)}$$ How can I extract module and phase and represent them?

Note that the module and phase of $1/z$ are the reciprocal of the module of $z$ and the negative of the phase of $z$, respectively. In case you don't know how to determine the module and phase of $x+\mathrm i(1+x)$, you might want to look at this.

Thank you. I forgot those properties that helped me solve the problem. –  Advicer Feb 8 '12 at 13:10
