Why inductor is central tapped in hartley oscillator?
In a Hartley oscillator, the inductor is center-tapped to create two inductive elements that can form a feedback loop necessary for oscillation. This configuration allows for a balance between the two inductors, enhancing the frequency stability and ensuring proper phase shift for sustained oscillations. The center tap also facilitates the use of fewer components while maintaining the required phase relationship, making the design simpler and more efficient.
What is the phase shift between voltage and current when an capacitance is connected to the circuit?
The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.
What is dyn11 and dyn12?
Dyn11 and Dyn12 are connection configurations for three-phase transformers, indicating the phase shift between the primary and secondary windings. In Dyn11, the primary winding is connected in delta (D) and the secondary in star (y), with a phase shift of 30 degrees, which is often used in step-down transformers. Conversely, Dyn12 also has a delta primary and star secondary but with a 30-degree phase shift in the opposite direction, making it suitable for specific applications where reverse phase shift is required. These configurations help in maintaining balanced loads and optimizing voltage regulation in power systems.

How do you generate an oscillator signal?
An oscillator is an electronic circuit that produces an electronic wave or signal. The oscillator signal is the signal the oscillator puts out. An oscillator can put out different frequencies and different types of waves depending on how it is designed. These signals have many different uses in electronics. For instance you can use it to convert DC (direct current) from a battery to 60 Hz AC (alternating current) to use in a home. Some oscillators are variable like what you have in your radio or TV for picking up different signals or stations. To produce an oscillator signal: if you know a lot about electronics you can build your own from parts you can get at some place like Radio Shack. Otherwise you can buy an oscillator. Radio Shack might have one or you might have to look on line. You also have to know what kind of wave and frequency you need to be sure and get an oscillator that produces that signal. If the signal you need is unusual you may need a variable oscillator.
Is hartley oscillator is better than colpitt oscillator?
Colpitt oscillator is better than hartley because colpitt produces less phase noise and uses capacitor instead of inductor as used in hartley oscillator which means that area is also saved.
What is mean by stability of the oscillator?
Stability of the oscillator means the how much frequency stability it have. Measure of frequency stability comes from "rate of change of phase w.r.t frequency", the more it is the more stable the oscillator is, because we know that one condition for oscillation is that the loop gain phase shift should be zero, hence if due to ckt. parameters there is some change in phase then by very little variations in frequency we can bring back the loop gain phase shift to zero. ex. is LC tank circuit which act as an osciilator at resonant frequency. Frequency stability can also be measure from quality factor, the higher it is the more stable ckt. is,Parikshit ParasherB-tech ECE, PG power engg.parikshit_parasher@yahoo.co.in
What is an RC oscillator?
AnswerOscillator that uses two passive elements for the timing. Namely resistor and capacitor.AnswerIt's an oscillator whose frequency-determining "tank" does not contain an inductive element, like a coil. These are good for extremely low frequencies--down to a few Hertz--but LC oscillators are better at radio frequencies.AnswerAn Rc oscillator is an oscillator that uses 3 or more phase shift networks, ( a network of a capacitor and resistor) as a frequency determining network (tank circuit) and a transistor to amplify that output, that only allows a certain frequency through by only letting the frequency that is able to shift 180 degrees out of phase through. And also has a feedback network from the collector (of the transistor) circuit, to compensate for circuit loss to oscillation.

What is the exact definition of differential phase shift keying?
differential phase-shift keying (′dif·ə′ren·chəl ′fāz ′shift ′kē·iŋ) (communications) Form of phase-shift keying in which the reference phase for a given keying interval is the phase of the signal during the preceding keying interval. Also known as differentially coherent phase-shift keying.Above retrieved from Answers.comViper1
Can Jacob Black's tribe in new moon shape shift?
they do not shape shift. they phase into werewolves. shape shifting implies that they can change into anything. they can only phase into wolves. they can also phase whenever they want, not just on full moons.
Working of transistor as an oscillator?
A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.

If an object is an oscillator if it exhibits linear motion?
Not necessarily. An oscillator is a system that tends to repeat a specific behavior or motion over time. While linear motion can be a characteristic of an oscillator, other types of motion such as circular or rotational motion can also be exhibited by an oscillator.
