Astable and Monostable Multivibrator Trainer
[attachment=18607]
Introduction
NV6507 Astable and Monostable Multivibrator Trainer has been designed specifically for the
study of Multivibrator in Astable and Monostable mode using IC NE 555. The board is absolutely
self-contained with in-built supply and pulse generator.
The Monostable Multivibrator, often called free-running multivibrator, is used for the generation of
well defined pulses. It provides a single pulse of desired duration in response to an external trigger.
Unlike the monostable multivibrator, astable multivibrator circuit does not require an external trigger
to change the state of the output.
The Astable Multivibrator, often called one-shot multivibrator, is frequently used as a simple means
of generating square and rectangular wave signal. It has no stable state.
Theory
The device 555 is a monolithic timing circuit that can produce accurate and highly stable time delays
or oscillations. The 555 timer is reliable, easy to use, and economical. IC 555 has been used in
number of applications, such as monostable and astable multivibrators, DC-DC converters, digital
logic probes, waveform generators, analog frequency meters and tachometers, temperature
measurement and control, infrared transmitters, burglar and toxic gas alarms, voltage regulators, etc.
