Abstract

This circuit provides an output waveform of constant duration in one state and of variable duration in the other state using a voltage to control the variable duration. The Fig. 1 circuit, consisting of comparator M1, resistors R1-R5 and capacitor C1, is a standard oscillator. The addition of transistor T1, diode D1 and resistors R6, R7 and R8 provides the control previously mentioned.
