How to Design Minimum-Phase FIR Filters
How to Design Minimum-Phase FIR Filters
by Matt Donadio
Like most things in DSP, there are several methods to create minimum-phase Finite Impulse Response (FIR) filters.
Cascaded Integrator-Comb (CIC) Filter Introduction
In the classic paper, "An Economical Class of Digital Filters for Decimation and Interpolation", Hogenauer introduced an important class of digital filters called "Cascaded Integrator-Comb", or "CIC" for short (also sometimes called "Hogenauer filters").
Here, Matthew Donadio provides a more gentle introduction to the subject of CIC filters, geared specifically to the needs of practicing DSP designers:

IIR Filter Basics
Infinite Impulse Response (IIR) filters are fundamental elements of Digital Signal Processing. This is dspGuru's mini-FAQ of "Frequently Asked Questions" on the subject of IIR filters.
1. IIR Basics
1.1 What are IIR filters? What does "IIR" mean?
IIR filters are one of two primary types of digital filters used in Digital Signal Processing (DSP) applications (the other type being FIR). "IIR" means "Infinite Impulse Response".
Multirate FAQ
Multirate DSP is a fundamental technique of Digital Signal Processing. Here, dspGuru provides "Rarely Given Answers" to "Frequently Asked Questions" about the important and mysterious subject of Multirate Digital Signal Processing.
