	Hybrid circuit - Patent 4301336
		The invention relates to a hybrid circuit for a transition from two-wire to four-wire lines and vice versa which is assembled from monolithic integrated differential amplifiers, preferably for electronic telecommunications and in particular, telephone exchanges controlled in accordance with a time multiplex method.
		In accordance with another feature of the invention, a symmetrical hybrid circuit with symmetrical four-wire inputs is formed of two configurations of the asymmetrical circuits connected together but having matching and balancing impedances with impedance values that are, respectively, one-half the impedance value of the corresponding impedances of an asymmetrical hybrid circuit.
		Although the invention is illustrated and described herein as embodied in a hybrid circuit, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

	Definition: hybrid coil (Site not responding. Last check: 2007-10-18)
		hybrid coil: A single transformer that effectively has three windings, and which is designed to be configured as a circuit having four branches, i.e., ports, that are conjugate in pairs.
		(188) Note: The primary use of a hybrid coil is to convert between 2-wire and 4-wire operation in concatenated sections of a communications circuit.
		Such conversion is necessary when repeaters are introduced in a 2-wire circuit.

	Prodigy Professional :: View topic - Fat recording console, circa 1944
		The main attraction of hybrid coil mixing, at least circa late '30s and early '40s, is that it can be arranged to have half the loss of conventional resistive mixing (e.g., 3dB of loss from summing two inputs as opposed to 6dB).
		Coil mixing can only be used with defined impedances on all ports; and even then, it's hard to maintain good isolation (trans-hybrid loss) between the ports across a wide frequency band.
		Coil mixing is a very cool idea, on the face of it, but the benefits don't seem to outweigh the drawbacks in 2004.

	PSN-L Message - Subject: Lehman damping
		THis uses the motion of the main signal coil to generate a voltage that induces a current in a resistor connected in parallel with it to dissipate the energy of the motion and thus damp it.
		It is the mechanical air-dashpot function of the coil movement, and is often listed in the specifications for the seismometer.
		For an L4-C, with a 5500 ohm coil, with G = 270 V/m/sec, Bo = 0.27, we want Bt to be 0.77, so Bem = 0.5, M = 1 kgm, omega = 2*pi (1 second) we calculate a damping resistor Rd of 6102 ohms for critical damping.

		hybrid A telecommunication term used to describe an interface box that converts a conversation (or data signal) coming in on two pairs (one pair for each direction of the conversation or signal) onto one pair and vice versa (i.e., a 2-wire to 4-wire converter).
		The name comes from the original use of a "hybrid coil" in the telephone whose function was to keep the send and receive signals separated.
		In analog designs leakage is reduced by modeling the impedance seen by the transmit amplifier as it drives the hybrid coil.

		A coil of wire produces a magnetic force on a flexible magnetic (usually steel) diaphragm, which flexes and causes a sound waveform.
		A coil of wire carrying the voice current produces a varying magnetic force on a flexible magnetic (usually steel) diaphragm, which flexes and causes a sound waveform.
		When audio waveform current flows from the microphone to the junction point in the split lower coil, it divides into two equal parts if the impedance of the matching network (ideally) is exactly equal to the impedance of the subscriber loop.

		The purpose of this research is to develop a hybrid coil system that combines the advantages of both surface coil arrays and volume body coils, combining high uniformity with high SNR.
		If data are acquired from all coils simultaneously, it appears feasible to correct the inhomogeneity associated with surface coil arrays while preserving their inherently high SNR.
		The main task is the development of a backward motion estimation algorithm that is a hybrid of the mesh-based and block-based methods.

		Is there perhaps some merit to the idea of not matching woofers and the upper range in a hybrid system, but rather aiming for a kind of complementary set of colorations that lock together so well that they synergistically make the more convincing whole?

		This subwoofer may very well handle a decent amount of power, and may sound good, but if you put a REAL 2400 watt amplifier on it, and turn it up to slightly over half volume, the only sound you will hear is your voice coil frying.
		But even MORE important are the number of voice coils and the impedence of the sub.
		The aluminum die-cast rib insert also direct-couples to the voice coil former to draw 50% of the heat away from the voice coil to the rib insert (heat sink) and strengthen the bond between voice coil former and the cone.
