Chebyshev Filter Design
This experiment was the design of another digital filter. In this experiment too we had to design Low Pass as well as High Pass Filter. Basically, the formula to find the order of the filter changed w.r.t Butterworth and various other input parameters were added. In this digital filter, the magnitude response was equiripple in the passband and monotonic(smooth) in the stop band. The number of valleys and peaks of the ripples equalled the order of the filter. In this filter design instead of convolution, recursion is used.
what are the advantages of chebyshev over other filter?
ReplyDeleteThe different filters have different properties, not
Delete'better' or 'worse'. The Chebychev filter of obtains a
steeper roll-off than a Butterworth filter of the same
order, which means the digital version of the Chebychev
requires less computational load, or the analog version
fewer components than the Butterworth. This cheaper or
simpler filter does not come for free, as the frequency
response contains ripples. Which may or may not be a
problem.
Which type of chebyshev filter you have used????

Deleteis chebyshev more complicated?
ReplyDeleteNot that much. Just start it
