DIGITAL-ANALOG CONVERTER CIRCUIT

摘要

A digital-analog converter circuit wherein in a pulse interval of input pulses a first capacitor is charged by a power source through a diode, and upon the application of an input pulse the electric charge stored in the said first capacitor is discharged through a grounded-base transistor and simultaneously a second capacitor is charged by the collector current of the said second capacitor is discharged through a resistor in the next pulse interval of the said input pulses.
