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 meant by free running frequency in phase locked loop?

The VCO is a special type of oscillator that has a frequency controlled by an applied voltage.The frequency of the VCO without any control signal applied is called the free running frequency.


What has a 555 timer IC in it so I can desolder it and use it?

The LM555 is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output circuit can source or sink up to 200mA or drive TTL circuits. There is little point in desoldering one since they are very cheap to buy since the chip is nearly thirty years old. NE/SA/SE555/SE555C Timer circuits are all over the net.


What is the operation of the monostable multiviator circuit using 555?

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.


How do u use PLL as FM detector?

To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.

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.


Which of transistor circuit is stable?

astable multivibrator type transistor is free running oscillator.so it has greater stablity . it can be varied by resistor and capacitor value

What are the differences between monostable and bistable multivibrators?

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.

What is the practical use of astable multivibrator?

it can be used any where, where we need the clock pulse train of low frequancy.like a function generator contains.astable multivibrator is used to produce waveformsas Astable means the circuit is not set to one state or the other but rather oscillates between those states. Therefore the application is signal generation
