Frequency response [2 Articles]
rendoddi - Nov 28 2007
Hi,
I have a problem on frequency response.
Suppose you have H(z)=B(z)/A(z), the transfer function of a digital
filter.
How do you calculate the ANALYTIC expression of the fi... 
Filter to remove noise from a corrupted song [3 Articles]
Farah Rasheed - Nov 18 2007
Hi everyone,
I have a question about filtering a noise signal in MATLAB. I have a
corrupted sound file and I loaded it in MATLAB and plotted the FFT of
the signal. From the FF... AAC psychoacoustic model

Hello
Can anyone give me an explanation how the covariance method for pitch detection in time domain works?
Thanks
