what is multivibrator?

The name mutivibrator designates a group of the circuits widely applied for switching as shift registers or temporary memories and as square were timing oscillator or clocks. These circuits are basically closed loop feedback circuits operating with the feedback.

Some of the uses of multivibrators are:

• They are used as a Frequency dividers
• Used as a saw tooth generators
• They are used as wave and pulse generators
• They are used as standard frequency source
• They are used in radar and tv circuits
• They are also used as a memory elements in computer

Applications astable multivibrator

• The astable or free running multivibrator is used as a square wave frequency generator
• As a timing oscillator or clock of a computer system.
• It is also used for a flashing lights, switching and power supply circuits.
