WebFigure 6. The complex function of a second-order all-pass filter. Higher-Order Filters. We are fortunate in not having to treat the higher-order filters separately, because a polynomial in s of any length can be factored into a series of quadratic terms (plus a single first-order term if the polynomial is odd). WebWhen I try to increase order (example : order=4 or even order=3 => number of poles=6), then the filter doesn't work anymore. Very quickly (after n=10 or 100), the signal is saturated to the max value : overflow ! (Nota : I work in double (64 bits) floating point). Somebody told that the higher the order, the more unstable!
