Oscillator circuit incorporated in the saw teeth and of the television receiver comprising such an oscillator

摘要

P the invention relates to an oscillator circuit, sawtooth signal generator. / p & & p & the adjustment of the saw teeth is necessary to intervene on the frequency and on the top and bottom thresholds of the teeth. The oscillator according to the invention comprises two comparators, one acting as a voltage reaches a predetermined threshold voltage, the other acting when the output current reaches a preset current threshold. The frequency setting is carried out by means of a variable resistor, connected between the output terminal and the reference potential. / p & & p & application to the saw teeth for vertical scanning television. / p
