Lab5:-Design of Butterworth Filter

The aim of this experiment was to design a Butterworth filter using Scilab software.As,Ap,Fs,Fp and sampling frequency were given as input parameters to the filter design and BLT method was used for filter design.The sampling frequency given as input was kept higher than 5 times the max(Fs,Fp). Magnitude response of the filter was plotted wherein frequency was kept in Hz and Magnitude in dB.It was observed that Magnitude response​ was monotonic (without ripple).

    Is the analog filter stable?If so why?

      Poles are on the left side of imaginary axis.

    As order increases characteristics of filter increases

      The frequency response becomes more sharp.

    If magnitude response is monotonic,spectrum is smooth and output magnitude can be calculated easily for a given value of frequency

    it is also referred as a maximally flat magnitude filter. The rate of falloff response of the filter is determined by the number of poles taken in the circuit

    They are called maximally flat filter

    Design of digital Butterworth filter can implemented using Impulse Invariant method also
