I'd have to know the inductance the gyrator is trying to simulate.
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
An oscillator has a tuned circuit (inductance+capacitance) to determine the frequency. When the inductor is tapped to give the required phase-shift for oscillation it is a Hartley oscillator. When the capacitance is tapped it is a Colpitts.
No, is it not permissible to synchronise two generators with no common electrical load to be exactly out of phase. Doing so would represent a double short circuit to both generators, and possible destruction of both generators. Whether it is possible or not depends on the design of the synchronizing circuit and/or the stupidity of the operator.
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
A tank circuit is an LC filter that, when at resonance, has an near infinite resistance. It is composed of an inductor in parallel with a capacitor. Resonance occurs when the magnitude of the impedance of the cap and inductor are equal. They have a fairly narrow bandwidth, which is why they are used in RF applications. They are able to 'focus in' on the desired frequency, and ignore the others. For example, if I have a simple tank circuit with a resonant frequency at 1 MHz connected to an unregulated ac function generator, and I measure the voltage across the tank circuit, when the frequency I apply is close to the resonant frequency, the amplitude of my output begins to increase. So at 900kHz, say, I might be getting 90% of the signal I apply to the circuit as my output. The impedance of this circuit increases as the frequency nears the resonance frequency of the tank. So if I set the function generator to 1MHz, the tank has extremely high impedance, and functions like an open, so I can expect my entire signal to drop across the tank circuit. Alternately, they can be used to create oscillators. Another name for a tank circuit which more useful for visualizing how it functions is the slosh circuit. When energy is applied to the slosh circuit, the cap will discharge into the inductor, and vise versa, and it will oscillate like this at the tanks resonant frequency. The energy 'sloshes' from one component to the other. This can be exploited by circuitry to make oscillators, amplifiers, voltage doublers and so on. I have not seen an RC tank circuit before, but one is theoretically possible using an active circuit called a gyrator, which consists typically of an op amp, a couple resistors, and a capacitor. A gyrator essentially makes one component function like another. If I construct a gyrator with a cap, it will function much like an inductor (not identically, there are a few differences), and likewise, I could make a psuedo-cap using an inductor based gyrator. So one could conceivably make a tank circuit using this gyrator in place of an inductor. But as far as practicality goes, I'm not sure how good of a substitute it would make, as the gyrator doesn't exhibit all of the properties of an inductor, and some active components can be quite sensitive to voltage, and extreme voltages are possible in a tank circuit configuration due to opposing phase shifts from the components. And, just to be pedantic, it would probably be called an RCQ tank circuit.
In both cases, the time constant of the RC circuit is increased. If the application is a high- or low-pass circuit, then the filter cutoff frequency is decreased in both cases. If the application is a phase-shift network, then the frequency for a given phase- shift is reduced.
The frequency of the power waveform in a capacitive circuit, or for that matter, an inductive circuit, is the same as the input voltage or current. Its just that the current leads the voltage (capacitor) or lags the voltage (inductor) by a phase angle, the cosine of which is the power factor. It does not matter how many sine waves you have, or what their phase angle is; if they all have the same frequency, the resultant, by Fourier analysis, is still a sine wave of the same frequency.
The phase shift angle of an RLC circuit is constant for a constant frequency, but changes with different frequencies.The phase angle of the AC in the RLC circuit is however continuously changing. Otherwise it wouldn't be AC.
Bandwidth does not change with frequency. Bandwidth defines (part of) how the response of a circuit changes with frequency. Other things that define how the response of a circuit changes with frequency are: phase shift, roll-off rate, linearity of the passband, etc. but bandwidth ignores these.
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
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.
A linear circuit is an electric circuit in which, for a sinusoidal input voltage of frequency f, any output of the circuit (current through any component, voltage across any component, etc.) is also sinusoidal with frequency f. Note that the output need not be in phase with the input.
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
