Abstract
In a time constant circuit of the type having a resistance capacitance circuit including a capacitor and a resistance network connected in series with the capacitor, wherein the improvement provides digital gate means having an output and at least one input, the output being electrically coupled to the resistance capacitance circuit, the digital gate means being adapted to provide a first digital output voltage level for charging the capacitor through the resistance network and a second digital output voltage level for discharging the capacitor through the resistance network, and circuitry connected to the input of the digital gate for controlling the output of the gate in response to the voltage charge of the capacitor.
