What is the difference between an astable multivibrator and a monostable multivibrator Mcq?
Explanation: Since, astable multivibrator is unstable and changes their states continually (It means that it can have both the states), whereas in monostable multivibrator, one of the states is stable, but the other state is unstable. SO Monostable Multivibrator is also known as Half-Astable Multivibrator.
What is the difference between astable monostable and bistable multivibrator?
Monostable – A one-shot multivibrator that has only ONE stable state as once externally triggered it returns back to its first stable state. Bistable – A flip-flop that has TWO stable states producing a single pulse either HIGH or LOW in value.
What is the difference between a monostable and an astable in a 555 circuit?
When the 555 timer is operating in Astable mode, then it requires an RC circuit consisting of two resistors and a capacitor. And in case of monostable mode of operation, the RC circuit comprises of a resistor and a capacitor.
Which multivibrator has two stable states?
bistable multivibrator
The bistable multivibrator A Bistable multivibrator has both the two states stable. It requires two trigger pulses to be applied to change the states.
What are the applications of Astable Multivibrator?
Applications of Astable Multivibrator Astable multivibrators are used in the applications like pulse position modulation, frequency modulation, etc. as they are simple, reliable and easy to construct. Get electrical articles delivered to your inbox every week.
What are the different advantages of monostable multivibrator?
Advantage of Monostable Multivibrator It needs only one single pulse to start its operation there is no need of extra pulse for its operation. Its construction is very simple and can be constructed easily. Due to simple construction its price is also less.
What is application of monostable multivibrator?
Applications of mono stable multivibrator The monostable multivibrator is used as delay and timing circuits. It is also used for temporary memories. It is often used to trigger another pulse generator. It is used for regenerating old and worn out pulses.
Which multivibrator is known as flip-flop?
NAND Gate Bistable Multivibrator
NAND Gate Bistable Multivibrator This type of bistable circuit is also known as a “Bistable Flip-flop”. The manually controlled bistable multivibrator is activated by the single-pole double-throw switch (SPDT) to produce a logic “1” or a logic “0” signal at the output.
What is main application of monostable multivibrator?
What is the application of astable multivibrator?
What are the disadvantages of monostable multivibrator?
One main disadvantage of “monostable multivibrators” is that the time between the application of the next trigger pulse has to be greater than the preset RC time constant of the circuit to allow the capacitor time to charge and discharge.
What are the advantages of astable multivibrator?
One of the major advantage is that they can work continuously.. They also the simple type of multivibrator. Also they are quite cheap one so they can be helpful financially.
What is the application of monostable circuit?
Monostable circuits are used as timers, pulse generators, waveform generators, and sweep generators for CRTs (cathode ray tubes) such as the ones found in some television (TV) receivers, older computer displays, oscilloscopes, and spectrum analyzers.
What is the application of monostable and astable multivibrator?
What is the main application of a monostable multivibrator?
Monostable multivibrators are generally used to increase the width of a pulse or to produce a time delay within a circuit as the frequency of the output signal is always the same as that for the trigger pulse input, the only difference is the pulse width.
Which transistor is used in astable multivibrator?
The basic transistor circuit for an Astable Multivibrator produces a square wave output from a pair of grounded emitter cross-coupled transistors. Both transistors either NPN or PNP, in the multivibrator are biased for linear operation and are operated as Common Emitter Amplifiers with 100% positive feedback.
What is the use of monostable multivibrator?
What is the difference between monostable and multivibrator?
The monostable is when after a trigger the output changes for a period and then returns to the base state. e.g After the trigger the voltage changes from 0Volts to 5 Volts stays there for a period and returns to 0 V. The period can be from nanoseconds to seconds dependin A multivibrator is a circuit that has two stable states.
What is the difference between astable and monostable?
The astable variety is when the output jumps between these two stable states continuously. This is usually known as an oscillator and is used for example as clocks to drive microprocessor circuits etc.. The monostable is when after a trigger the output changes for a period and then returns to the base state.
What is a monostable circuit?
A monostable circuit is an electronic device called a multivibrator that has two distinct states, one of them stable (having a steady voltage) and the other one unstable (having an unsteady or variable voltage). After the delay time t has elapsed, the monostable circuit returns to the low state.
What is the difference between bi-stable and astable?
Bi-stable, mono-stable, and astable. The bi-stable needs a stimulus/trigger to change its state, regardless of its existing state. The mono-stable produces one output pulse each time it receives a trigger. The astable is free running and produces a continuous output of pulses.
