- dfilt. df2sos - Discrete-time, SOS, direct-form II filter - MATLAB
hd = dfilt df2sos(b1,a1,b2,a2, ) returns a discrete-time, second-order section, direct-form II object, hd, with coefficients for the first section given in the b1 and a1 vectors, for the second section given in the b2 and a2 vectors, etc

In summary, the DF-II structure has the following properties: It can be regarded as a two-pole filter section followed by a two-zero filter section It is canonical with respect to delay This happens because delay elements associated with the two-pole and two-zero sections are shared

Combining these two block diagrams yields the direct form II diagram shown in the following figure Notice that the feedforward part (top of block diagram) contains the numerator coefficients and the feedback part (bottom of block diagram) contains the denominator coefficients

First, we create a data structure for the cascade IIR stage, containing filter coefficients and filter state We will use a direct-form Type II design, which gives us a state of only two variables
