		A series circuit containing R, L, and C is in resonance when the current in the circuit is in phase with the total voltage across the circuit.
		Parallel resonance is the condition that exists in an AC circuit containing inductive and capacitive branches when the total current is in phase with the voltage across the circuit.
		A plot of the transfer function for this network is similar in appearance to the series RLC circuit because the output is taken off the parallel LC part of the circuit.

		If the circuit is then disconnected from the battery and the open terminals are shorted out, the capacitor discharges by sending a current through R that is in the opposite direction of the charging current.
		The RL circuit is also an energy storing device: Faraday's law of induction as applied to the self-induction of a coil shows that the coil is opposing the free flow of current as the magnetic field is being built.
		This is used for signal discrimination: an RLC oscillator picks out of the mixture of radiosignals (received on the antenna) the one that comes in with the frequency that agrees with its natural frequency.

		The effective RLC circuit is drawn on the front of the box, indicating the positions of the R, L, and C, but not the isolation transformers.
		In a series circuit such as this the current in all of the elements must be the same amplitude and in the same phase.
		Near the resonance this means that their impedance is somewhat greater than that of the components used in the RLC circuit itself, so they do not have a significant effect on the properties of the basic RLC circuit.

	RLC Filters
		Objective: The objective of this lab was to review how capacitors and inductors work together in an RLC circuit and to observe the frequency dependence of gain in theses AC circuits.
		The circuit is called a low pass RC filter because it allows low frequencies to pass through, but for high frequencies it acts like a short circuit across the capacitor, which attenuates those frequencies.
		For the final part of this experiment we constructed a circuit similar to that of the last part, except the capacitor and inductor are in series rather than in parallel.

	Series RLC Circuits
		When we add a resistance to a series LC circuit, as shown in the schematic diagram to the right, the behavior of the circuit is similar to the behavior of the LC circuit with no resistance, but there are some variations.
		Since this is a series circuit, the current is the same through all components and is therefore our reference at a phase angle of 0°.
		One effect of adding R to the circuit has been to reduce the current through the circuit, and increase the circuit impedance.

	Window-Based Susceptance Models for Large-Scale RLC Circuit Analyses
		Due to the increasing operating frequencies and the manner in which the corresponding integrated circuits and systems must be designed, the extraction, modeling and simulation of the magnetic couplings for final design verification can be a daunting task.
		This can result in an RLC circuit size that is impractical for traditional simulators.
		A critical aspect of this simulation efficiency is owed to a susceptance-based circuit formulation that we prove to be symmetric positive definite.
