Abstract

A noise shaper for shaping a power spectral density of an input signal which consists of signal intervals, wherein each signal interval has a corresponding signal amplitude being constant for a variable interval duration time of the signal interval, said noise shaper comprising a calculation unit having at least one serial connected integrator wherein each integrator calculates an integrated signal of different order from said input signal, and a weighting unit for weighting each integrated signal with a corresponding adjustable weighting coefficient according to a noise transfer function.
