multivibratoreid

Multivibratorid are electronic circuits used to implement a variety of simple memory functions or two state systems. They are characterized by having two states, with transitions between these states being triggered by external signals or internal timing. The term "multivibrator" was coined by Henri Abraham and Eugene Bloch in 1919. These circuits are fundamental building blocks in digital electronics and have a wide range of applications.

There are three main types of multivibrators: astable, monostable, and bistable. An astable multivibrator, often called a free-running multivibrator, has no stable states and continuously oscillates between two unstable states. This makes it suitable for generating clock signals or square waves. A monostable multivibrator, also known as a one-shot multivibrator, has one stable state and one unstable state. It remains in its stable state until triggered by an external pulse, at which point it transitions to its unstable state for a predetermined duration before returning to its stable state. This is useful for pulse shaping or delay generation. A bistable multivibrator, commonly referred to as a flip-flop, has two stable states. It will remain in one stable state indefinitely until an external trigger causes it to switch to the other stable state, where it will then remain until another trigger is applied. Bistable multivibrators are the basis of memory elements in digital systems, capable of storing a single bit of information.
