Which oscillator is more accurate Mcq?
In the following oscillator which one is more accurate? Explanation: The stray third capacitor in the clap oscillator doesn’t have a negative effect and the frequency obtained is instead more stable and accurate than colpitt oscillator.
Which oscillator is more stable Mcq?
Explanation: Crystal oscillator gives the most stable oscillation.
Which is the stable oscillator?
A Crystal oscillator has much better frequency stability than LC or RC oscillators. It has a very high Q-factor. A crystal oscillator is basically a tuned – circuit oscillator using a piezoelectric crystal as a resonant tank circuit.
What are the three types of oscillation?
Examples
- Double pendulum.
- Foucault pendulum.
- Helmholtz resonator.
- Oscillations in the Sun (helioseismology), stars (asteroseismology) and Neutron-star oscillations.
- Quantum harmonic oscillator.
- Playground swing.
- String instruments.
- Torsional vibration.
What is the formula of oscillation?
The period formula, T = 2π√m/k, gives the exact relation between the oscillation time T and the system parameter ratio m/k.
What is meant by free oscillation?
1 : the oscillation of a body or system with its own natural frequency and under no external influence other than the impulse that initiated the motion. — called also free vibration.
What are oscillators Mcq?
Oscillators are devices known for converting the signals DC into AC. Any amplifier can be converted to an oscillator by giving a feedback connection. An amplifier for amplification prefers negative feedback and provided with positive feedback results in oscillations.
Which oscillator has best frequency stability?
The oscillator with the best frequency stability and accuracy is
- Hartley oscillator.
- Colpitts oscillator.
- Tickler feedback oscillator.
- Crystal controlled oscillator.
What will be the Clapp oscillator?
The Clapp oscillator or Gouriet oscillator is an LC electronic oscillator that uses a particular combination of an inductor and three capacitors to set the oscillator’s frequency. LC oscillators use a transistor (or vacuum tube or other gain element) and a positive feedback network.
Why we use Wein bridge oscillator?
A Wien bridge oscillator is a simple circuit that can be set to continuous oscillation, which outputs a sine wave. The Wien bridge oscillator acts as a useful reference oscillator for analog circuits, and the output signal can then be manipulated with other analog circuits.
What is meant by Q factor?
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. … Q factor is alternatively defined as the ratio of a resonator’s centre frequency to its bandwidth when subject to an oscillating driving force.
Which oscillator is used for high frequency?
The LC Oscillator is therefore a “Sinusoidal Oscillator” or a “Harmonic Oscillator” as it is more commonly called. LC oscillators can generate high frequency sine waves for use in radio frequency (RF) type applications with the transistor amplifier being of a Bipolar Transistor or FET.
Which oscillators are more suitable at high frequency?
LC oscillators provide good frequency stability and generate a good sine wave at high frequencies. Frequency stability i.e. frequency of oscillation does not change very much for change in supply voltage or ambient temperature.
What is difference between oscillation and vibration?
Oscillation vs Vibration
Oscillation is a definite distance covered by the movement about its equilibrium position, vibration is referred to the physical change brought about due to movement of the body. Oscillation can be seen in the swinging of a pendulum clock and vibration in the plucking of guitar string.
What is wave oscillation?
A wave is said to oscillate, which means to move back and forth in a regular, repeating way. This fluctuation can be between extremes of position, force, or quantity. Different types of waves have different types of oscillations. Longitudinal waves: Oscillation is parallel to the direction of the wave.
What is oscillation in simple words?
Oscillation is the process of moving back and forth regularly, like the oscillation of a fan that cools off the whole room, or the oscillation of a movie plot that makes you laugh and cry. Oscillation is from the Latin word oscillare for « to swing, » so oscillation is when something is swinging back and forth.
What is difference between oscillation and SHM?
All oscillatory motions are periodic motions but all periodic motions are not oscillatory. … Simple harmonic motion is a straight line motion and it requires a restoring force.
What is the unit of oscillation?
Periodic motion is a repetitious oscillation. The time for one oscillation is the period T. The number of oscillations per unit time is the frequency f. These quantities are related by f=1T f = 1 T .
What are free oscillation give an example?
An example of free oscillations is the motion of a simple pendulum in a vacuum. A damping oscillation is one in which the moving particle gradually loses its kinetic energy on interaction with resistive forces like air or friction.
What is difference between damped and free oscillation?
The free oscillation possesses constant amplitude and period without any external force to set the oscillation. … But in all-natural systems damping is observed unless and until any constant external force is supplied to overcome damping. In such a system, the amplitude, frequency and energy all remain constant.
What are free oscillations give two examples?
Some examples of free vibrations are oscillations of simple pendulum, oscillations of object connected to a horizontal spring, sound produced by tuning fork in short distance, notes of musical instruments, organ pipe, etc.
What are oscillators Mcq Sanfoundry?
Explanation: An oscillator is an amplifier with positive feedback. It usually has a noise which is an amplifier as an oscillating output. They do not require any type of specific input to function properly. Explanation: Negative resistance are incorporated in oscillator for sustained oscillation.
Which law is obeyed in oscillators?
6. For practical oscillators, which law has to be obeyed? Explanation: For an oscillator circuit, it has to obey the Barkhausen criteria, otherwise the output f the oscillator will tend to zero as the time advances. 7.
What is IC 723 MCQ?
This set of Analog Circuits Multiple Choice Questions & Answers (MCQs) focuses on “Voltage Regulators – 1”. … Explanation: The IC 723 is a voltage regulator, which can act as both a low voltage regulator as well as a high voltage regulator. Output can be set between 7-37 volts. 7 volts is the reference starting voltage.
