Abstract

A digital timer with constant resolution comprising a clock and a chain of binary down-counters, each of which corresponds to a timing range which is a mutiple of that of the preceding down-counter. The binary outputs of the down-counters are fed in parallel to display points of a first set of display points, enabling means being provided so that only the output of the most significant down-counter not at zero actuates the display points. A display point of a second set of display points is associated with each down-counter so that only the display point corresponding to the most significant down-counter not at zero is actuated.
