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