"WebA high order filter, i.e. a filter with many poles (and maybe zeroes) can have theoretically better (i.e. closer to ideal) performance, but it is more complicated and expensive to implement, and it is more susceptible to degraded performance when any of the polynomial coefficients are slightly off-spec. This means high order filters are finicky. " - High order filter projects
