Description
сто щей из последовательно соединенных резистора 8 и конденсатора 9, средн точка которой подключена к базе транзистора ключа 7, позволит осуществл ть автоматическое включение генерации мультивибратора при включении питани .A resistor 8 connected in series and a capacitor 9, the midpoint of which is connected to the base of the transistor of the switch 7, will allow automatic switching on the generation of the multivibrator when the power is turned on.
При включении питани положительный скачок напр жени через конденсатор 9 прикладываетс к базе транзистора ключа 7. Транзистор ключа 7 открываетс и эмиттер транзистора 6 оказываетс подключенным к нулевой шине источника питани . По мере зар да конденсатора 9 напр жение на базе транзистора ключа 7 уменьшаетс , достигает порога срабатывани , транзистор ключа 7 отключаетс и эмиттер транзистора 6 подключаетс к источнику управл ющего напр жени .When the power is turned on, a positive voltage jump across the capacitor 9 is applied to the base of the transistor of the switch 7. The transistor of the switch 7 opens and the emitter of the transistor 6 is connected to the zero line of the power supply. As the capacitor 9 charges, the voltage at the base of the transistor of the switch 7 decreases, reaches the threshold, the transistor of the switch 7 turns off, and the emitter of the transistor 6 is connected to the control voltage source.
