The two-element LC circuit described above is the simplest type of inductor-capacitor network (or LC network). It is also referred to as a second order LC circuit [ 1 ] [ 2 ] to distinguish it from more complicated (higher order) LC networks with more inductors and capacitors.
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
An LC circuit can be quantized using the same methods as for the quantum harmonic oscillator.An LC circuit is a variety of resonant circuit, and consists of an inductor, represented by the letter L, and a capacitor, represented by the letter C.
Figure 10 shows a band-stop filter formed by a series LC circuit in shunt across the load. Figure 11 is a band-stop filter formed by a parallel LC circuit in series with the load. The first case requires a high impedance source so that the current is diverted into the resonator when it becomes low impedance at resonance.
Position vector r is a point to calculate the electric field; r ... LC circuits: Circuit equation + = Circuit equation + = (+) Circuit ...
Whereas the value of the capacitive coupling coefficient of resonant LC-circuits is always negative. In accordance with (6), the formula (5) for the capacitive coupling coefficient of resonant circuits takes a different form = (+) (+). (7)

The voltage across the tuned circuit is approximately ±Vbe peak relative to ground. The source-coupled oscillator uses two junction FET and a LC-circuit to produce a sine wave signal. L1 and C1 are the LC-circuit, J1 is a common drain amplifier, J2 is a common gate amplifier. The grid-leak C2, R2 connects the LC-circuit to J1 input.
