Recursive digital filter comprising at least two digital delay devices, a multiplying device having two inputs which are coupled to one another in a common branch point, a summing device from which a sum signal is derived the magnitude of which is at least equal to the sum of the output signal of the multiplying device, and a feedback circuit connected between the output of the summing device and the distribution point. The feedback circuit is provided with a discarding device which acts on numbers given in sign-and-magnitude representation and which by means of magnitude truncation restricts the number of bits of the numbers applied to the branch point.
