Digital recursive filter of modified Meerkötter-Wegener structure, with preset signal word length, in floating-point arithmetic, the signal being subjected, after evaluation or addition, to a cutting or rounding operation, the input or output signal of the delay components each being subjected to a saturation characteristic, and the input or output signal of the delay components or of the limiters, or the signals which are conducted back to the input of the delay components, being subjected to a signal correction such that if the signal or the evaluation coefficient is negative, an amount of 1 to 3 times its quantisation step is added to or subtracted from this signal. <IMAGE>
