hi guys,
i'm relatively new to dsp but im trying to learn. I wrote a convolution function for audiofiles in matlab. Just out of interest i convoluted white noise with a discrete dirac, and compared the frequency response of the convoluted white noise (outputsignal) with the orignial white noise (input signal). for frequencies around 20 - 200 Hz there are very small differences. with higher frequency the responses become identic, like it should be. the length of the convoluted signal is signal + dirac. i noticed when the length of the output signal is equal to the length of the input signal, i get a completely identic frequency response. I would greatly appreciate if anybody could explain this to me!
regards
