An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
A bistable device is the foundation of digital electronics. A bistable device is a device that can exist in one of two possible states,which could either be on or off. .
An astable multivibrator [also known as an oscillator] is a circuit built so that it does not come to rest in one single state but switches between them continuously.
Multivibrators are the regenerative circuits used in timing circuits. The are classified as Bistable Multivibrators, Monostable Multivibrators and Astable Multivibrators.

Bistable wave is a one-dimensional wave whose profile connects two stable equilibria asymptotically approaching one of them at minus infinity and the other one at infinity. In… contrast, waves connecting one stable, one unstable equilibrium are called monostable.
it is about thefiltering of the ac signal from the circuit. when transistor2 switched on, collector terminal is suddenly shorted to ground and voltage at collector2 drops to v…ce from vcc.it cause a negative voltage pulse. the negative pulse coming at the collector of 2nd transistor passes to base of 1st transistor and thus transistor1 is switched off. commutating capacitors will allow to pass the ac signal only. so the negative pulse at the 2nd collector alone is feed to the base of 1st transistor. that is function of commutating capacitor
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 o…ne-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.
oscillators could generate various types of waveforms, i.e., sinusoidal, triangular, etc. Oscillators generating non-analog waveform(sinusoidal, triangular are examples of ana…log waveforms) ,i.e., square or rectangular waveforms are called multivibrators. Classically, "multivibrator" term was proposed by the Dutch physicist van der Pol, refers to the multiplicity of harmonics in the spectrum of generated oscillations (in this sense a generator of sinusoidal oscillations could be called a monovibrator).
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 consta…nt 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...
schmitt trigger is also know as
Schmitt trigger refers to an input hysteresis mechanism to improve the noise tolerance of a digital input, preventing glitch generation or false triggering on outputs. A bist…able multivibrator is a flipflop, a device capable of storing one bit.
