From: Jean Hernandez on 24 May 2010 15:15 Hi! I have a simple system, for the input I know the fft and for the system I know how the frequency response, the problem is that the response is no linear, it represents the bahaviour of an electrical circuit, the complication is that the circuit paramenters vary with the frequency. So I think that just a multiplication of the spectrums is not enough since the non lineariies. I'm thinking in solving the problem using a spectrum convolution but I'm not sure and have found it dificult to find information about the topic. If you have some lights about please let me know that I'd really appreciate it.
