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.
Can you use astable multivibrator as a inverter?
An astable multivibrator cannot be directly used as an inverter, as its primary function is to generate a continuous square wave output rather than to invert a signal. An inverter, or NOT gate, takes a single input and produces a single output that is the logical opposite of the input. However, if you configure an astable multivibrator to oscillate at a frequency where the output toggles between high and low states, it can mimic a simple inversion under specific conditions, but this is not its intended use. For true signal inversion, dedicated inverter circuits are recommended.
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 the advantage of astable multivibrator using 555 ic over those made with opamp or bjt?
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.
What jobs can a transistor do when combined with the CPU?
The modern CPU (typically inside a microprocessor IC) is built of billions of transistors (typically complementary MOSFETs). The CPUs of the late 1960s were built of tens of thousands to hundreds of thousands of transistors inside several hundred MSI ICs (typical silicon NPN BJTs). The CPUs of the late 1950s to early 1960s were built of thousands to tens of thousands of discrete transistors (typically germanium BJTs, gradually transitioning silicon BJTs). The CPUs of the early 1950s did not use transistors, they were built of hundreds to tens of thousands of vacuum tubes.

Why you use NPN transistors rather than PNP?
Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.

How do you change frequency astable?
To change the frequency of an astable multivibrator circuit, you can adjust the values of the timing components - typically resistors and capacitors. Increasing the values will decrease the frequency, while decreasing the values will increase the frequency. Alternatively, you can also adjust the supply voltage or use a different type of oscillator circuit to achieve the desired frequency.

Why you use majority NPN transistor but not PNP transistor?
please send the answer...................... answer: people are positive animals we think positive +5v for instance is the predominate voltage in a computer PNP will work fine on a -5v environment but +5 volt is here to stay so NPN transistors are predominate
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.
Why use of Multivibrator?
it gives a nice pleasurable experience
How monostable multivibrator can be used to generate?
we can use monostable multivibrator.But generally its o/p is a square wave so to get a pulse type waveform,we may use differentiator after monostable multivibrator....
How do you use ne555?
The NE555 timer can be used in various configurations, primarily as an astable, monostable, or bistable multivibrator. In the astable mode, it generates a continuous square wave output, useful for clock pulses or LED flashing. In monostable mode, it can produce a single pulse output of a specified duration when triggered, ideal for timer applications. To implement it, you typically connect resistors and capacitors to the appropriate pins based on the desired operation mode and calculate the timing values using the formulas provided in the datasheet.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
