A time-discrete amplitude-continuous or a time-discrete amplitude-discrete signal (i) is converted into a 1-bit encoded signal by means of a quantizer (14), the quantization-error signal being fed back via a loop filter (28). The transfer function of the loop filter is given by H(Z) = 1 - (Z-b)<n>/(Z-a)<n>, where n >/= 3, b SIMILAR 1 and 0 < a < b. In order to preclude instabilities the input signal of the loop filter (28) is limited by a limiter (23).
