IPC: H03M13/23
Filed: 1990-12-17
Abstract: A circuit array (18) comprises a plurality of add/carry/select (ACS) circuits (20-23) which operate in parallel to perform an operation required to implement convolutional coding for error correction in a digital communications system. The ACS circuits (20-23) are commonly used in Viterbi decoders. Each ACS circuit of the array operates in serial form with single bit-wide adders which function to implement addition of branch metrics, comparison of accumulated metrics, selection of the smallest accumulated metric for each state in a state machine and maintaining a path history to each state. As a result, interconnect ions between the ACS circuits (20-23) are minimized.

Abstract: A holographic storage system receives light having its linear polarisation rotated from a reference linear polarisation for carrying given information. The modulated light is stored as two distinct images in a photorefractive medium (10), the images carrying the same information but being complementary projections of linear polarisation rotations from the reference linear polarisation in a given rotational sense. The images are stored in the same volume portion of the medium. Upon readout, the two images arte converted into modulated electrical signals (Px, Py). To reproduce the information, one of the modulated electrical signals is divided into the other modulated electrical signal. A function of arc tangent of square root is introduced into the signal processing at the output portion of the system.

Abstract: A new data communications architecture is disclosed in which high level communications services provided to a host processor (104) are arranged into independent horizontal functions (105-1...105-N) that are processed in parallel. Any conditional dependencies among the horizontal functions are resolved by a connector (106) that interfaces the horizontal functions to an application layer (101) of the host processor. Additionally, communication performance is enhanced by allowing adaptive specification of a high-level protocol employed in the architecture for providing the high-level services. This adaptive specification may be initiated in response to changing user requirements or varying network parameters. Then, a high-level protocol specification is obtained by choosing appropriate values for parameters of the horizontal functions which are parametrically programmable.

Abstract: A phase demodulator for directly demodulating carrier PSK signals, PSK-modulated with digital signals, without using any analog circuit. Where the invention is applied to a demodulator of the differential detection type, the baud timing signal is converted into a synchronous baud timing signal, synchronized with the first leading edge of the PSK signals converted into "1" or "0" in logical level. Meanwhile, the ring oscillator generates signals of a frequency substantially equal to the carrier frequency of the PSK signals, and generates outputs at N taps. The outputs obtained at the N taps have a 2π/N phase difference between every pair of mutually adjoining taps, and are latched with the synchronous baud timing signal in each baud period. The point at which the logical level of mutually adjoining latch outputs varies from "1" to "0" is the phase information of said digital signals. The corresponding phase information is encoded to constitute the demodulated output. In a demodulator of the synchronous detection type, meanwhile, the latch outputs are used as said phase information like in the case of the differential detection type. The reference phase of the PSK signals is fixed by subtracting from this phase information the offset phase, which is the output of the synchronous phase fixing circuit.

Abstract: In a method of producing a compound semiconductor device, a semiconductor layer which makes no alloy with a metal electrode that is to be disposed thereon but makes an ohmic contact with the metal electrode is formed as an uppermost layer in a lamination of epitaxial layers, an ohmic electrode which is easily removed by chemical etching is deposited thereon, a first insulating film is deposited thereon, a groove is formed by chemical etching at a region where a gate is to be formed to expose an active layer, a second insulating film is deposited thereon and etched to form insulating side walls on the internal surface of the groove, and a gate electrode whose shape is regulated by the first insulating film and the side walls is formed. Therefore, the gate electrode and the source electrode are formed self-alignedly with each other, and the interval between the gate electrode and the ohmic electrode is reduced to the width of the side wall, whereby the source resistance is reduced. In addition, since the operation layer, i.e., the uppermost semiconductor layer is not damaged during the formation of the groove, a compound semiconductor device with high performance and high reliability is achieved.

With respect to the test image data, a meandering recognition block Φ D  having the same shape as that of the block Φ is set at a position corresponding to the block Φ set with respect to the reference image data. A difference ΔP(Φ) between a sum P(Φ) of output data of all pixels included in the block Φ and a sum P(Φ D ) of output data of all pixels included in the block Φ D  is calculated. A difference ΔP(Φ n ) between a product of the output P(B) and a pixel count  n  of the block Φ in the direction Y and a product of the output P(A) and the pixel count  n  is calculated. A meandering amount and direction of the web are obtained on the basis of the absolute value and the sign of a quotient obtained by dividing the difference ΔP(Φ) by the difference ΔP(Φ n ).
