ABSTRACT:
A cathode-ray tube display comprising a control unit whose intensity control output, horizontal sweep control output and vertical sweep control output are coupled, respectively, to the data input of an intensity control unit, to the counting input of a first Fibonacci code pulse counter, and to the counting input of a second Fibonacci code pulse counter, the output of the intensity control unit being coupled to the data input of a cathode-ray tube, data outputs of the first and second Fibonacci code pulse counters being coupled, respectively, to the inputs of first and second pulse amplifiers via first and second Fibonacci code digital-analog converters, fault acknowledgement outputs of the first and second Fibonacci code pulse counters being coupled via a checking OR gate to the fault acknowledgement input of the control unit, and transient outputs of the first and second Fibonacci code pulse counters being coupled via a blanking OR gate to the blanking input of the intensity control unit.
