Web9 jun. 2024 · The BLT method helps to avoid aliasing of the frequency response that you may encounter while using the Impulse Invariance method to obtain your filter values by mapping one-to-one from the s-plane to the z-plane. Hence, using this method lowers the sampling rate required significantly compared to the IIR method. Web1. Sure there is. The simplest version would be to calculate the transfer function of your FIR filter, sample it on some meaningful frequency grid and then shove it into invfreqz () to design the IIR filter. Depening on you FIR filter this may work well or be a total disaster.

WebIntroduction to IIR Filter Matlab. IIR filter is a type of digital filter used in DSP (Digital Signal Processing) applications; it is an abbreviation for “Infinite Impulse Response.” For the IIR filter, the response is “infinite” as there is feedback in this type of filter.
