This session involved analyzing analog and digital butterworth filter. We used Scilab for creating a code for filter design. Then we entered the input parameters in the console of Scilab. Finally we obtained the output which is the magnitude response. We have compared the attenuation values and order of the filter. Implementation on Scilab is very helpful as we learned the code while debugging it.
Butterworth filter has ripple free passband and stopband
ReplyDeleteGood explanation
ReplyDeleteButterworth filter has many applicatioins due to its smooth graph.It is also called as maximally flat filter and its rolloff depends upon the number of poles
ReplyDeleteWell explained
ReplyDeleteBest when very sharp frequency response is not required but passband needs to be completely flat
ReplyDeleteRipple free frequency response
ReplyDeleteButterworth is monotonic
ReplyDeleteOrder of Butterworth filter is more than that of chebyshev filter
ReplyDeletePrecise
ReplyDeleteButterworth filter is also called maximally flat magnitude filter
