Hi Sushmita,

I understand that you want to design a IIR Biquad filter. You can do so with the help of 'dsp.BiquadFilter' object, in which IIR filter is designed using biquadratic structures. The direct form of the filter can be specified in the 'Structure' input property of the object. Please refer to the following documentation link for more details on the filter object:

dsp.BiquadFilter

Hope it helps!
