This function generates a Bessel filter.
[a, b] = besself(n, w) [a, b] = besself (n, w, "high") [a, b, c] = besself (…) [a, b, c, d] = besself (…) […] = besself (…, "z")
positive integer value
positive real value
This is an Octave function. This function generates a Bessel filter. The default is a Laplace space (s) filter. The third parameter takes in high or low, the default value being low. The cutoff is pi*Wc radians. [z,p,g] = besself(...) returns filter as zero-pole-gain rather than coefficients of the numerator and denominator polynomials. [...] = besself(...,’z’) returns a discrete space (Z) filter. w must be less than 1. [a,b,c,d] = besself(...) returns state-space matrices.
