lattice constant the length of the sides of the three dimensional unit cell in a crystal. lattice structure a filter used in linear pre- diction that has two outputs, the forward pre- f m [n] and the backward predic- tion error g m [n]. These two error signals are defined recursively: f m [n] = f m−1 [n] + K m g m−1 [n − 1] g m [n] = K ∗ m f m−1 [n] + g m−1 [n − 1] where the K m are the called the lattice coef- ficients of the predictor. lattice vector quantization (1) a struc- tured vector quantizer where the reproduc- (2) vector quantization, where codewords represent prototype vectors arranged in a reg- n-dimensional space. lattice VQ See law of excluded middle a logical law stat- ing that for Boolean variable X, X must be either Z or not Z. law of the first wavefront See layout specifies the position and dimen- sion of the different layers of materials as LC-oscillator a type of oscillator that is practical at the frequencies above 50 kHz and g m and drain-source impedance r o is shown as an example; it can be substituted by a bipolar X 1 and X 2 are coils, the mutual reactance X m should be considered as well). The frequency of oscillation is given by the condition X 1 + X 2 + X 3 + 2X m = 0 and the threshold condition for self-starting g m r o R L r o + R L ≥ X 2 + X m X 1 + X m If X 1 is a tuned coil in the gate, X 2 is the drain coil, 2 X m is the mutual inductance between the two coils, the circuit is called tuned-gate LCD See LCI See LCLV See LDD See lead a conductive path, usually self- supporting; the portion of an electrical com- lead circuit a simple passive electronic circuit designed to add a dominant zero to c 2000 by CRC Press LLC |
