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.
No triggering is used on an astable multivibrator because it can cause it to become unstable.
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
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.
astable network means it has only one stable state.so the circuit need trigger input to change to another stage and it automatically changes to the previous stage when the process completed with the use of the capacitor.
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.

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 type transistor is free running oscillator.so it has greater stablity . it can be varied by resistor and capacitor value
no stablestate
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.
An astable multivibrator does not require an input clock, therefore can be described as "free-running" in that its running without a reference.
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
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.
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.

digital generator nothing but square wave generator or astable multivibrator
No. Household wiring requires household wiring.
