This chapter deals with the design methods in which a desired frequency response is approximated by a transfer function consisting of a ratio of polynomials. In general, this type of transfer function ...
This section introduces a pole-zero placement method for a simple IIR filter design. Let us first examine effects of the pole-zero placement on the magnitude response in the z-plane shown in Figure ...
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 ...
