2. Choose a filter design method: There are various methods available for FIR filter design, such as windowing, frequency sampling, and least squares. The choice of methoddepends on the desired filter characteristics and design constraints. Continuing with our example, I decide to use the windowin...
The so-called “window method” for FIR filter design is also based on the convolution theorem for Fourier transforms. The polyphase filter bank (PFB) is a type of FIR filter for mitigating the aforementioned drawbacks of the straightforward DFT. The PFB not only produces a flat response ...
