Applications of Astable Multivibrator



1. The Astable Multivibrator circuit mainly used as a continuous wave generation circuit.

2. Astable Multivibrators are used in Frequency Modulation Circuits.

3. Astable Multivibrators are used in analog as well as digital timer Circuits.

4. They are also used in Voltage to Frequency converter circuits.

5. Astable Multivibrator circuit can generate also Square Wave, for this reason, they are used in digital transmission, receiver, television broadcast, etc.

6. They are used for pulse synchronization or pulse position modulation.



7. They are used as timing oscillator or clock in a computer system.

8. They are used in Radio Equipment such as Transmitter and Receiver Circuit.

9. In earlier days, astable multivibrators are used for morse code generation.

10. They are used in digital Flip-Flop Circuits, Electronic Register Circuits.

11. They are used in flashing lights, automatic switching circuits.

12. They are used for speed control of DC motor with Pulse Width Modulation Technique.


Advantages of Astable Multivibrator



1. They are very simple in design.

2. They are very reliable.

3. They are very easy to construct with a very low cost.

4. They do not need any external triggering.

5. They can run continuously for a very large amount of time without any problem.



Disadvantages of Astable Multivibrator


The continuous pulse generation by this multivibrator circuit depends upon the positive feedback. So due to the resistance in the circuit, this multivibrator cannot transfer the whole output signal to the input. So a small amplifier circuit is used with this multivibrator circuit which restores the lost energy.

  Unmanned Power Sub Station System An Unmanned Power Substation System refers to a modern and technologically advanced electrical substation that operates without the need for constant on-site human presence. These unmanned substations utilize automation, remote monitoring, and control technologies to efficiently manage potential events. Automation and Remote Control The system is equipped with intelligent devices and sensors that automate various tasks such as monitoring voltage, current, temperature, and other parameters. Remote control capabilities allow operators to manage the substation from our command center. Reduced Operation and Maintenance Costs With the elimination of on-site personnel, the operational and maintenance costs associated with manned substations are significantly reduced. Routine maintenance tasks can be scheduled and monitored remotely. Enhanced Reliability and Safety The use of automated systems ensures greater reliability and minimizes the risk of human ...

Difference Between AC And DC Motor

  Difference Between AC And DC Motor The difference between AC and DC Motor are discussed below: AC Motor vs DC Motor AC Motor DC Motor AC motor runs on alternating current. DC motors operate on direct current. There is no need for conversion of current in AC motors. Like AC. There is no need for conversion of current in AC motors. Like AC. AC motors are used where power performance is demanded for extended periods of time. DC motors are used where the speed of the motor needs to be controlled externally. AC motors can be single-phase or three-phase. All DC motors are single phase. In an AC motor the armature does not rotate while the magnetic field keeps rotating continuously. In a DC motor, the armature rotates while the magnetic field rotates. Repairing AC motors is not expensive. DC motors are very expensive to repair. Brushes are not used in AC motor. Brushes are used in DC motor. AC motors have a very long life span DC motors do not have a very long life span. The speed of AC...

  What is MOSFET? The MOSFET, also known as a metal-oxide-semiconductor field-effect transistor, is a type of FET with an insulated gate that is assembled by the controlled oxidation of that  semiconductor . The semiconductor used in it is generally silicon. In more detail, we can explain that it is a four-a terminal-based device that is composed of a, Source(S) Gate (G) Drain (D) Body (B) In a general overview, the body of a MOSFET is in connection with its source terminal hence forming a three-terminal device such as a field-effect transistor. It is normally considered a transistor and is utilized in both digital circuits and analog circuits. A MOSFET can function in two ways Depletion Mode Enhancement Mode Enhanced Mode Enhanced mode can be defined as if there is no voltage across the gate terminal then the device will not conduct. But when there is a maximum voltage present across the gate terminal then the conductivity of the device gets enhanced. Depletion Mode Depletion...
