Abstract
A digital input signal having a sampling frequency f is interpolated by a factor N, where N is a positive integer, whereby a first digital signal having a sampling frequency Nf is generated. A non-linear operation is carried out on the first digital signal having the sampling frequency Nf and a second digital signal having the sampling frequency Nf is provided. The second digital signal is decimated by the factor N and thereby provides a digital output signal having the sampling frequency f.
