Learning Experience : Butterworth Filter

This lab was different because in this session we were implementing filter in Scilab.we used scilab for filter designing because plotting phase or magnitude plot in much easier than c.thanks to inbuilt Scilab function plot(x,y).We learned that the Butterworth filter is monotonic in it's pass band as well as stop band i.e. it does not have any ripples.also to get ideal i.e. rectangular frequency response we should keep order of filter infinite.but in actual designing we keep as high as possible.
