In many applications, you need to apply a post-processing digital filter on your data. A common example is the filtering of data from an ADC. This application note shows an IIR filter that can be ...

Maximally flat digital filters (MFDFs) are widely applied in applications where the energy of useful signals is concentrated around some specific frequencies. A typical design method of MFDFs is to ...

Due to the nonlinear and multimodal nature of infinite impulse response filter coefficient spaces, achieving stable and accurate identification remains a challenging task in digital signal processing.

Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.
