Abstract
A family of efficient and practical interpolators for interpolated FIR (finite-impulse-response) filters using cyclotomic polynomials is presented. The interpolators can be applied to bandpass filters as well as lowpass/highpass filters without multiplications. They mitigate the inconvenience in selecting a practical interpolation factor: consequently, the novel family provides for a further saving in computational complexity. Some design examples are given
