A partial clue to the answer is in its name, Monostable. i.e. it has one stable state.
This is, in most monostables, a low, or "zero" state.
When a monostable receives a trigger, it produces one output pulse, the width (duration) of which is determined by the suitable choice of associated components.
Once the pulse has ended, the monostable returns to its stable state, ready to be triggered again.
The most common use is for 'de-bouncing' switch contacts.
Mechanical switches rarely make a clean contact first time. With modern high speed electronics, the 'crackle' from switch contacts can be detected as many separate presses of the switch. Follow the switch with a monostable and it will only detect one press over a short period of time.
A monostable multivibrator is a circuit which produces a single pulse of specified duration in response to each external trigger signal.
I would use two 555 timer ICs. Hook the first one up as a monostable multivibrator and the second as an astable multivibrator. The first one sets the length of duration and the second sets the frequency of the tone. Go to your local bookstore and get a copy of "IC Timer Cookbook" by Walter G. Jung. This is an excellent book and will describe the pinouts and methods of assembly.
No triggering is used on an astable multivibrator because it can cause it to become unstable.
In a digital circuit probably the best way is with a monostable multivibrator, or one shot timer. The length of the timer should be made to be just a little longer than the bounce time of the switch. Ans2: My favourite is a 2 input NAND gate with both inputs connected to the switch, but with a small RC delay circuit in one of them.
The bistable multivibrator, or flip-flop, will stay in one or the other state indefinitely, until it is told to change state. The monostable (or astable) multivibrator, or one-shot flip-flip, will stay in one state indefinitely, but once set to the other (triggered) state, it will remain there for only a certain time. There are two varieties. The non-retriggerable one-shot will generate a pulse of known width when triggered, and will complete its cycle no matter what the input does. The retriggerable one-shot will generate a pulse of variable width, minimum being the base time constant, and the pulse can be extended (retriggered) as desired.
we can use monostable multivibrator.But generally its o/p is a square wave so to get a pulse type waveform,we may use differentiator after monostable multivibrator....
how can we modify the monostable multivibrator to obtain triangular wave generator
No, the output of monostable multivibrator does not oscillate. As it has only one stable output we do not get oscillations. We get a square wave as output.
A monostable multivibrator is a circuit which produces a single pulse of specified duration in response to each external trigger signal.

applications of monostable multivibratorA monostable is a circuit that will respond to a stimuli only once and only for a period. Its usage can be many depends of applications

Free-running or relaxationoscillators
No, cant use bistable multivibrator in place of monostable multivibrator... because monostable is meant for one stable state and one unstable state.. so there will be a constant time period for the alternate pulses of output.. but in bistable multivibrator, both are stable states.. so there is no specific time period for the output pulses.. the state will vary only on the application of mannual trigger...
it is used for square wave generation.\ ANSWER: Never monostable is a once fire will never toggle again. Meaning it will work once and never again not until a stimuli is present again. there AS-TABLE oscillators and monostable
Monostable multi vibrator has got one stable state. Its pulse duration depends on the resistor and capacitor values used. By changing these values, the pulse duration can also be changed. Hence the circuit can be used for pulse control.
