www.staff.ncl.ac.uke.g. Butterworth, Chebyshev, or Elliptic, and then transforming the resulting filter to get the desired frequency response e.g. high-pass, band-pass, or band-stop. This is accomplished by substituting the frequency-domain transfer function H(s) with one of the relevant frequency transformations listed below.

arxiv.orgThe Chebyshev polynomials are recursively defined as T k(x) = 2xT k 1(x) T k 2(x), with T0(x) = 1 and T1(x) = x. The reader is referred to Hammond et al. (2011) for an in-depth discussion of this approximation. Going back to our definition of a convolution of a signal xwith a filter g
