ABSTRACT:
A digital delay line supplies from a periodic input signal n signals with the same period mutually shifted by one n-th of the input signal period. The digital delay line includes n cells, each of which includes m delay elements in series, each output of a delay element being connected to an input of a multiplexer. The output phase of the n-th cell is compared with that of the input signal phase. The output of a multiplexer of the n cells is modified after each comparison.
