摘要： An FIR digital filter device of the symmetrical coefficient type or the antisymmetrical coefficient type which processes digital data signals such as digital audio signals. In the FIR digital filter device, an input digital data is transferred in the forward direction through a plurality of digital signal processors (F, B) connected in cascade and is then transferred in the reverse direction to form M pieces of delayed digital data. The digital signal processor in each stage effects the algebraic addition of said delayed digital data and the input digital data through a first operation unit (46), effects the multiplication through a multiplier (47), adds up the multiplied result through a second operation unit (37), and transfers the obtained data as carry-over data to the next stage.

摘要： A method and a device for recording and reproducing digital signals by which digital signals for normal reproduction and a plurality of kinds of digital signals for special reproduction are time-sequentially recorded on a tape-like recording medium and the recorded signals are reproduced. The data rate of the digital signals for normal reproduction is detected. Either the digital signals for normal reproduction or those for special reproduction are selected in accordance with the detected data rate and recorded in a prefixed area on a recording medium for recording the digital signals for special reproduction. The time-sequentially recorded digital signals are reproduced and identified as the digital signals for normal reproduction or those for special reproduction. The identified digital signals are separately outputted. The tape-like recording medium has a track pattern composed of a plurality of tracks on which the digital signals for normal reproduction and the plurality of kinds of digital signals for special reproduction are time-sequentially recorded. The track pattern has a first area in which the information representing a prefixed position where the plurality of kinds of digital signals for special reproduction are recorded and a plurality of second areas in which either the digital signals for normal reproduction or those for special reproduction are selectively recorded in accordance with the data rate of the digital signals for normal reproduction at positions represented by the information recorded in the first area.

摘要： An information recording medium is provided with a first signal recording area (A) in which first data are recorded, and second signal recording area (B) which is provided outside the area (A) and in which second data including the same information as that of the first data are recorded at a density higher than the recording density of the first data. The recording density of the second data can be two to ten times as high as that of the first data. The sampling rate, the number of quantizing bits, and the number of picture elements of the second data may be larger than those of the first data. In addition, the first data may be recorded at a fixed transfer rate and the second data may be recorded at a variable transfer rate. The first data may be music signals in an audible range, and the second data may be music signals in an ultrasonic range outside the audible range.

摘要： A vertically anisotropic medium or a vertical recording system for conducting unoriented recording. The system has a terminal for receiving binary signals that are to be recorded, a ring head for causing magnetic change in the medium, and a recording current generating circuit for generating a recording current that drives the ring head. The recording current is a sequence of fine pulses whose polarities change in response to the direction of change of polarities of the binary signal, and nonzero intervals of a neutral level are inserted between the neighboring fine pulses having opposite polarities relative to each other. The pulses are given a duration TW which satisfies a relationship TW

摘要： A voice signal generator which records at least portions of the signals repetitively onto a video disc such that they will be reproduced as normally reproduced voice signals at the time of normal reproduction, the signals being recorded onto the video disc which stores a first composite video signal of the same field or a second composite video signals of the same frame of a movie film on each track turn repetitively over a plurality of field periods, and which, at the time of normal reproduction, produces a normally reproduced image describing a scanning locus accompanied by a forcible change of track of a pick-up reproducing element. A recorded voice signal of a first recording medium on which has been recorded in advance a voice signal separated from a TV signal, is reproduced at a speed lower than that of the time of recording, and is elongated on a time axis into M times (M is a rational number greater than 1). On this signal is superposed at least part of the data that is formed based upon clock signals that are in synchronism in phase with periodic signals in said first or second composite video signals, and that are compressed on a time axis into 1/M. Continuous voice signals that are compressed on the time axis are recorded onto the second recording medium together with the first or second composite video signals that have the same field or the same frame over said plurality of field periods.
