Hi everybody:
I'm trying to analyse equations of analogue electronic filters, but i can't get the "norm" of the complex polynom if i use variables (or symbols? what's the difference?), here's the simplest exemple (RC low pass filter, a represents R*C*w, reals variables > 0):
Assuming[ a \[Element] Reals && a > 0, Norm[1/(1 + a \[ImaginaryJ])]]
Norm[1/(1 + I a)]
The answer :
Norm[1/(1 + I a)] ----- the same thing!
Re[] and Im[] doesn't work either!
I will like to uses to find the argument (Arg[] doesn't work)
and after all, make my bode plots!
please help me, I'm new in mathematica!
Thanks
