how to convert function from time domain to frequency domain?

hello i have this function: H(w)=(1+a)/a+bz+c while a,b,c are function that dipend on 'w' like a=jwc b=cosh(w*l) so there is any furier transform so i can find the time filter of the transmitaion function? thanks!

Compute H(w) for a range of values of w and then use the fft function to compute the frequency spectrum. There is an example provided in the documentation, adapt it to your data.
