Digital filter arrangement in which a sample of an output signal is calculated by forming the sum of the products of a set of samples of an input signal and a set of filter coefficients. To provide a more accurate encoding of the filter coefficients without great consequences for the hardware, the filter coefficients are encoded by combinations of the form: K1x2m+K2x2n, wherein n and m are integers and it holds that for at least one coefficient: 1<¦K1¦<2 and ¦K2¦=0 or 1 or: 1<¦K1¦<2 and 1<¦K2¦<2 and a multiplier is present for combinatorially multiplying a signal sample by the factor ¦K1¦, ¦K2¦ which is located between 1 and 2.
