  • Abstract
    A simple procedure, applicable to any high order transfer function (n¿3), is described, which generates a family of transfer functions possessing identical phase/frequency responses but distinct gain/frequency responses. By application to a 10th-order all-pole Bessel function, it is shown that selected members of this particular family have significantly wider gain-bandwidths and correspondingly improved time domain behaviour.
