N2 - In this paper a computationally cheap method is proposed to filter a harmonic series where the first harmonic is a sine at the fundamental frequency f1 and the super harmonics are sines at frequencies 2f1, 3f1, 4f1.... The method is based on multirate filter banks. With this method a large amount of IIR notch filters can be implemented much more efficiently than by simply staggering single rate IIR notch filters without deteriorating the frequency range of interest.
