i do not know what an astable circuit does thats why i aksed
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.
555 an IC which can be used for many applications and one of the application is astable multivibrator. For many applications we use IC 555 because its cost effective and have lot of features.The main difference is astable multivibrator switches from one state to another state automatically i.e when a pulse is given to astable multivibrator, it immediately switches to high state and remains for certain time and switches back to low state. In 555timer you can decide your own application.
The 555 timer IC is a device that can create various kinds of time delays in a circuit. It uses a threshold pin that is typically connected to an RC circuit. Depending on how it is connected, it can operate in one shot mode (monostable), astable mode (retriggerable), or schmitt trigger mode.
The 555 timer is commonly used in IC electronics and in electronic circuits. In the monostable multivibrabor mode, the 555 works as a pulse generator. In astable mulitvibrator mode, the 555 is free running, and goes back and forth between frequencies.
an oscillating RC circuit
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.
A 555 chip is used as a timer. In a monostable circuit the chip will send one pulse after a period of time. If the chip is in a astable circuit it will send pulses forever.
To bypass Resistor Rb to get less than 50% duty cycle.
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
frequency drops
well the formula is frequency=1.44/(r1+2r2)c1
The difference is in the name. "Mono" means one, so a monostable circuit is a circuit that is only stable in one state. An astable "A" means without... is a circuit that is not stable in any state. hope this helped!

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.
