The list of digital filtering toolkits is given below. MatDeck provides several toolkits which enable digital filter designing in a graphical environment, which is very convenient for many users.

FIR filters: firfilter(), initfirfilter(),firfreqresp().

IIR filters: iirfilter(), initiirfilter(), iirfreqresp(), iirgrpdelay(), iirphasedelay().

The MatDeck software contains a variety of different functions for both IIR and FIR filter design and analysis. There are three main categories of digital filters: the recursive filters otherwise known as infinite impulse response (IIR) filters, and the nonrecursive filter otherwise known as finite impulse response (FIR) filters. Furthermore, a digital filter can be used to extract the signal within a certain frequency range, which is one of the most important role frequency selective digital filters. For example, a digital filter can be used to attenuate noise, DC bias etc.

In digital signal processing, a digital filter is a system that performs mathematical operations on a discrete-time signal to either reduce or enhance certain aspects of that specific signal.
