Abstract
PURPOSE:To obtain a pulse signal whose duty cycle is about 1:1, by converting horizontally oscillating pulse signals into pulses through an operational amplifier after they are converted into sawtooth waves. CONSTITUTION:Horizontal oscillating pulse signals applied upon an input terminal 1 are integrated by a integrator 2 and converted into sawtooth wave signals. An operational amplifier 4 detects 50% points of the crest value of the sawtooth wave signals, converts them into pulse signals having a duty cycle of about 1:1, and then, delivers them to an output terminal at the secondary side of a transformer for output 8. When this circuit is used, pulse signals whose duty cycle is always constant even when the frequency of the horizontal oscillating pulse signal is changed, can be obtained.
