among the chebsew and butterworth filter which is more
efficient?

Answer Posted / sivanvitha

Compared with a Chebyshev Type I/Type II filter the
Butterworth filter has a slower roll-off, and thus will
require a higher order to implement a particular stop band
specification,
But Butterworth filters have a more linear phase response
in the pass-band than Chebyshev Type I/Type II
