ABSTRACT:
An AC display excitation and synchronous display updating circuit for a digital electronic instrument in which the counter accumulating clock pulses representative of the magnitude of the quantity to be represented on the digital display is used as a frequency divider to obtain an AC display energizing signal whose frequency is reduced from the clock frequency to a suitable level for energizing the display. The contents of the continuously driven counter are synchronously transferred to the display register at the end of the conversion cycle by the use of a two-phase clock.
