How does the phase-shift oscillator get its name?
Phase shift oscillator consists
Can solve the harmonic oscillator expectation value?
second quantazation of harmonic oscillator
What is Franklin oscillator?
It is an electrical oscillator which uses two transistors or vacuum tubes and a LC circuit. The two transistors are connected as a two stage amplifier, both stages are inverting. the output of the second is coupled to the input of the first by a tuned circuit. Provided the amplifiers have enough gain, the circuit will oscillate, because the two amplifiers each give 180 degree phase shift, so the output is in phase iwth the input, so the oscillations build, until they are limited in amplitude by gain compression.

What device can give the output without taking any input?

How can an amplifier become an oscillator?
An amplifier can become and oscillator by adding positive feedback from the output back to the input. Positive feedback means that the phase of the signal fed back to the input is the same as the phase of the output signal. In the case of a high frequency oscillator, a tuned circuit (inductor and capacitor) or a quartz crystal in the input circuit will determine the frequency of oscillation.
Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
How an amplifier can be converted to a oscillator?
By introducing positive feedback from output to input
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
What is the difference between oscillator and multivibrators?
Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input
Why you go for wien bridge oscillator?
It generates an oscillatory output signal without having any input source
What is amplifier and oscillator?
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.
What is the oscillator?
The purpose of an oscillator is to produce repetitive sound that will compliment the music being played. They are relatively easy to set up and use. Oscillators will filter the sounds providing a wide range of music.
Why PLL better than VCO?
A PLL is different than a VCO. Each has its own use. Actually a PLL (Phase Locked Loop) contains a VCO (Voltage controlled oscillator). A VCO is an oscillator whose frequency is related to an input voltage. You can use it when you need a varying frequency that is controlled by a varying voltage. But it is not great at outputting a consistant exact voltage because it is very sensitive to its environment (e.g. temperature). A PLL will "lock" its output frequency to some input frequency. So it can oscillate at a frequency that is controlled by an input oscillator. Not too useful if the output frequency is the same as the input. But the output frequency can be divided before it is compared to the input. This allows the output frequency to be higher (some multiple of) the input frequency. Once a PLL is "locked on" to an input frequency it can be very stable.
How are FM signal generated?
There are several methods for generating FM signals but they all basically involve an oscillator with an electrically adjustable frequency. This type of oscillator uses an input voltage to affect the frequency of its output. For example, when the applied voltage increases, the oscillator output frequency increases and when the applied voltage decreases, the oscillator output frequency decreases as well. If no voltage is applied to the oscillator its output will be a signal at its centre frequency. The amount of frequency variations is deviated around the oscillators' centre frequency.
