In this experiment, using analog filter parameters like Passband and Stopband Attenuation, Analog Passband and Stopband Frequency as well as sampling frequency we designed digital Butterworth Low pass and High Pass filter.
We conclude that the frequency bands of analog and digital filters are complex and they don't match. The advantage of this filter is that the Magnitude spectrum is monotonic in both passband as well as stop band.

Crisp information about the topic!
ReplyDeleteThere are no ripples in the pass band and stop band of Butterworth filter
ReplyDeleteYes its monotonous means there are no ripples.
DeletePrecise explanation!
ReplyDeletedetailed information
ReplyDeleteButterworth filters have higher order compared to Chebyshev filters for the same parameters.
ReplyDeleteThe flat passband avoids differences in gain in the information signal.
In Butterworth filter as we go on increasing order of filter, response becomes more sharper and at approaches to ideal response.
ReplyDeleteIt's a ripple-free filter
