We implemented Butterworth filter using attenuation and frequency in stop and pass band and sampling frequency.By using blt method we got the normalised filter for it and denormalised according to the filter .Thus filter was designed after taking its ZT. From the graph we concluded that there are no ripples found in either stop or pass band and with increase in order the slope becomes sharper.

With higher order roll off in transition band becomes steep
