Abstract
An evaluating circuit for evaluating square wave signals is provided. A plurality of square wave signals are transmitted to a memory which has a number of bistable toggle stages which correspond to the number of square wave signals. The toggle stages are driven by an auxiliary clock signal. An up-down counter is also driven by the auxiliary clock. The circuit further includes a comparator which compares the square wave signals and the state of the up-down counter and generates a control signal over at least one control line to the up-down counter in response to the comparison. The state of the up-down counter is changed in an up or down direction or not changed in response to the control signal.
