Abstract
A process and apparatus for improving the resolution of square, subdivided signals by synchronizing the signals with an auxiliary clock signal. The signals are further conditioned by switching logic elements which, in dependence upon adjacent signals in the subdivision order and upon the auxiliary clock signal, only allow the states of the signals to change at predefined times.
