Typically, in FIR filter design the length of the filter will need to be specified. I won't get into the details much further on FIR filters and their pro's and con's as this tutorial focuses more on designing filters fast and efficiently with the aid of Octave. As the series progresses, it will discuss the necessary steps to implement the filter on real hardware.Ī FIR filter is a digital filter whose impulse response settles to zero in finite time as opposed to an infinite impulse response filter (IIR), which uses feedback and may respond indefinitely to an input signal.The great thing about FIR filters is that they are inherently stable and can easily be designed to have linear phase. This tutorial will focus on designing a finite impulse response (FIR) filter.
