Why no triggering is used for astable multivibrator?

No triggering is used on an astable multivibrator because it can cause it to become unstable.

Why astable multivibrator called free running oscillator?
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
What is astable multivibrators?
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.
What is the role of capacitor in an astable multivibrator?
The capacitor charges up with the current flowing through a resistor. The time taken is well defined by the capacitance and the resistance, and these components control the frequency.
How can you continuously generate a tone for a certain duration?
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.
What is meant by monostable multivibrator?
A monostable multivibrator is a circuit which produces a single pulse of specified duration in response to each external trigger signal.
Why do you use npn transistors in an astable multivibrator?
You can create an astable multivibrator with PNP, NPN, FETs, or even with NOR gates, NAND gates, or NOT gates. In fact the escapement movement in a mechanical watch is a species of astable multivibrator.
Astable multivibrator can be used as?
An astable multivibrator such as simple 555 timer circuit can be used as a clock source, turning LEDs on/off at timed intervals, or at frequencies between 20hz-20khz to generate sound audible to humans
How many state in astable multivibrator has?
no stablestate
How DC is converted to square pulse?
The easiest way to convert the DC Voltage to pulse is simple astable multivibrator. This can be achieved either directly by astable multivibrator ic's or using normal transistor and resistor combination circuits or by using 555 as astable multivibrator.
Why astable multivibrator called free running oscillator?
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
What is the use of a astable multivibrator?
1. It is used for the performance of many digital operations such as counting and storing binary information. 2. It is also used in the generation and processing of pulse-type waveforms.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.
Difference between monostable multivibrator and astable multivibrator?
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...
What is astable?
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.
What is astable multivibrators?
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.
What is the function of a digital generator?
digital generator nothing but square wave generator or astable multivibrator
Can an astable multivibrator replace household wiring if the circuit is modified?
No. Household wiring requires household wiring.
Is output of astable multivibrator using 555 AC or DC?
it's ac; astable multivibrators are unstable in both of their two states, so they switch back and forth, switching the polarity of the circuit.
