摘要： In a noise controller which forms a noise cancelling sound having a phase opposite to and a sound pressure equal to those of a noise infiltrating into a closed space, any deviation in its transfer characteristics from the initial equalization is easily checked and judged owing to the provision of an adaptive filter which automatically varies the filter coefficient and forms a cancelling signal for forming a cancelling sound, a coefficient updating means which updates the filter coefficient based on an error signal after the noise has been cancelled, a simulated transfer characteristics compensation means which forms the initial equalization by simulating transfer characteristics of a transmission path via the space in which the noise is to be cancelled and forms a reproduced reference signal, a white noise generating means which generates white noise to check the initial equalization, and an initial equalization judging means which judges the accuracy of the initial equalization based on a ratio (S/N) of the reproduced reference signal obtained from white noise to the error signal. A change in the conditions for cancelling noise is detected in the closed space, and any deviation from the initial equalization is judged.

摘要： A noise control device disposed at the outlet of a tail pipe which emits exhaust noise of an automobile to silence noise from the tail pipe comprises a speaker which is arranged near the tail pipe and of which the open surface has a constant angle with respect to a vertical plane, an enclosure which closes the rear portion of the speaker, and a silencing sound guide portion which guides silencing sounds emitted from the front surface of the speaker to the outlet of the tail pipe. A closed space into which a bumper for absorbing impact in case of collision is made, is used as a resonant-cavity of said speaker. Based on the amount of silencing noise which becomes greater as a plurality of microphones are arranged to be closer to the speaker, the outputs of the plurality of microphones apart a constant distance from said speaker are synthesized.

摘要： A digital signal processor comprises a code converter which converts an integer coded in a Binary Two's Complement (BTC) code to an integer coded in a Sign Magnitude Binary (SMB) code and/or a code converter which converts the SMB code to the BTC code. An integer coded in the BTC code and stored in an m-bits register is converted to an integer coded in the SMB code and input to an n-bits register, by an EXCLUSIVE OR processing of the bits with the sign bits and by supplementing a logic "1" in the less significant bit next to the least significant bit of the result of the exclusive OR operation. An integer coded in the SMB code and stored in an n-bits register is converted to an integer coded in the BTC code and input to an m-bits register, by an EXCLUSIVE OR processing of m-1 bits of magnitude bits with a sign bit. The code converters have a relatively simple construction, will not output an incorrect result, and are most suitable for processing AC signals.

摘要： A data transfer apparatus transfers serial data to and from a controller. The apparatus includes a first memory which stores at least one of command data and address data of the serial data transferred from the controller, and a second memory which stores a main body portion of the serial data to be transferred to and from the controller. Changeover circuitry is provided which selectively applies the serial data transferred from the controller to either the first memory or the second memory. Further, the changeover circuitry applies a clock signal received from the controller to one of the first memory or the second memory in accordance with a latch signal received from the controller. The second memory functions to selectively store the main data portion of the serial data received from the controller and to read the main data portion of the serial data transmitted to the controller.

摘要： When transferring data between plural electronic apparatus, the apparatus are composed so as to transfer floating decimal point data possessing the mantissa portion and exponent portion. Therefore, when transferring fixed decimal point data not having such divisions, a vacant time is left in the composition responsible for transfer, and the number of channels of the input/output data is limited unreasonably. To solve such problems, an apparatus it is designed to store, as well as to input and output, the fixed decimal point data also in the exponent portion storage region other than the mantissa portion storage region in the apparatus for storing fixed decimal point data.

摘要： The enclosure of the receiver device is divided into an antenna vicinity enclosure 1 and a demodulation unit enclosure 2, which are connected by a single transmission cable. By disposing the antenna vicinity enclosure 1 in the vicinity of the antenna, the high frequency feeder cable drawn from the antenna to the antenna vicinity enclosure 1 can be shortened. The effect of pulse noise and high frequency noise picked up by the conventional feeder cable can therefore be reduced. Furthermore, the length of the feeder cables in a quantity corresponding to the number of antennas is then reduced and the wiring space for the feeder cable can be reduced. The demodulation unit enclosure 2 is disposed spaced apart from the antenna, and the wiring space for the transmission cable can be greatly reduced in comparison with a case where a plurality of feeder cables are wired in the wiring space.
