Multivibrator Circuit Diagram. When a transistor is on it works in saturation region and its collector emitter acts as a short circuit. Please do read the article transistor as a switch.
But when it is off they acts as open circuit. Please read the article transistor as a switch to know more about it. The led on the right side is lit when the transistor on the right side q2 is on.
Inverters 1 and 2 widely used to form the astable circuit which has a continuously variable frequency range of roughly 0 5 to 511z.
But when it is off they acts as open circuit. Please do read the article transistor as a switch. Astable multivibrators are the most commonly used type of multivibrator circuit. The circuit diagram is shown in fig 2.
