DISPLAY INHIBITION MEANS FOR DYNAMIC MULTI-DIGIT DISPLAY IN TWO-SPEED ULATORS OR THE LIKE

摘要

Two-speed calculators and the like employing an arithmetic processor and a time-sharing multi-digit display are clocked with high frequency pulses during an arithmetic mode and with low frequency pulses during a subsequent display mode. Display inhibition means are provided within the twospeed calculators to create cut signals effective to erase spurious indications on a multi-digit display. The display inhibition means are under control of the high frequency pulses and operate to control the pulse width or phase of the cut signals.
