hi, I am trying to implement digital FIR filter in my DSP kit. I don't know how to calculate the FIR coefficients. I know the order, sampling frequency and my signal bandwidth. I want to design Multi band pass filter. Can anyone help me in this regard and may be e mail me the procedure. It would be very much grateful. My id is (t...@yahoo.com) Thanks.

Hi all. I have a question about a issue here. I want to convert a non-linear IIR filter to a linear FIR filter as well as= applying a window to it. It seems like I'm doing it wrong as frequenserespons I get of my new filter= never goes to zero (or close to zero) in the stopband, as well as the band= pass does not look good either. the code: b_window =3D hanning(100); [b,a] =3D but...

Dear all, Currently, I am working on implementing recursive low pass filter with design equation extracted from manual y(n) = 2*y(n-1) - y(n-2) + x(n) - 2*x(n-3) + x(n-6) The frequency response of the filter is good. However, the manual also mention, in act

Hi, I am currently working on a speech enhancement project. I am implementing a noise cancellation system using Wiener filter. > From what I read in the text books and from the net , I got the transfer function for the filter as h(f) = {psd(noisySignal) - psd(noiseSignal) }/psd(noisySignal). I implemented this in matlab ,but the result was a highly distorted signal. I have given my proced

Hello Folks At the moment I am trying to design a one pole simple IIR digital filter to simulate thermal heating and cooling delay effect with simple equations like 1 - e^(-t/T), where T is a known time constant. I think an one pole IIR filter will do it: Y[n]

Dear all, I am working on the recursive frequency sampling filter design. My confusion is, I read the theory saying that as it contains the poles.and also exactly pole zero cancellation occurs to give the stability. in case of fir filter using remez or any,

Hi, I am tring to resolve a probleme with an EMQF filter with the order 9 but i can't find the correct function to address this kind of filters. I have found on a site that a function that addresses this kind of filters is apellip_du ( i am adding the link to this information so that anyone who will want to help me, will check it out if they don't belive me) but this functions didn't work in neit...

This MATLAB program is for making a suitable wavelet kernel It derives the Low pass filter by sampling from analog raised cosine function in frequency domain and taking ifft from this function to yield the impulse response. (other filters are derived using orthogonal relations). first i wnat know if the filter design method has any problems? The filter has 2 parameters in frequency domain ...
