Function File: […] = besself (…, "z") ¶

Generate a Bessel filter. Default is a Laplace space (s) filter.

[b,a] = besself(n, Wc) low pass filter with cutoff pi*Wc radians

[b,a] = besself(n, Wc, ’high’) high pass filter with cutoff pi*Wc radians

[z,p,g] = besself(...) return filter as zero-pole-gain rather than coefficients of the numerator and denominator polynomials.

[...] = besself(...,’z’) return a discrete space (Z) filter, W must be less than 1.

[a,b,c,d] = besself(...) return state-space matrices
