摘要： A sampling rate converting method and apparatus for converting the sampling frequency of a 1-bit digital data obtained a .SIGMA..DELTA. modulator to 32 kHz, 48 kHz, 96 kHz or 192 kHz without producing jitter. A decimation filter 3 decimates the sampling frequency of 1-bit digital data of 2.8224 MHz supplied from an input terminal 2 by 1/2-tuple decimation. An interpolation filter 4 oversamples the frequency of the output of the decimation filter 3 by quintuple oversampling with an integer ratio of 1:5. A decimation filter 5 decimates the frequency of the output of the interpolation filter 4 by 1/21-tuple decimation with an integer ratio of 21:1.

摘要： An audio signal recording and reproduction apparatus enabling a low frequency band signal component to be reproduced by existing reproduction apparatuses and a high frequency band component to be processed as well. A digital audio signal is divided into a low frequency band signal component and high frequency band signal component by a frequency band division filter. The low band signal component is subjected to straight PCM processing to maintain compatibility with existing reproduction methods. The high frequency band signal component is subjected to high frequency coding through a requantization circuit and entropy coding circuit. A comparison circuit compares the straight PCM signals and the high efficiency coded signals to determine if they will fit into a predetermined bit length and, when not fitting, causes the requantization circuit to perform requantization to shorten the bit length. The bit redistribution circuit performs redistribution between the straight PCM bit data and the high efficiency coded bit data. The wave data is recorded on a CD. On the CD may also be recorded the sub-code data of an entropy coding circuit and the number of requantization bits of a requantization circuit.

Feed lines from the radio frequency transmission and reception circuits are connected to the first earth plate, respectively. Ground lines of the feed from the radio frequency transmission and reception circuits, respectively, are connected to the second earth plate. Thus, vertical exciting currents flow at both end portions of the second earth plane, enabling transmission and reception of vertical polarization waves.

摘要： A motorcycle-detecting device according to the present invention is mounted on an automotive vehicle. The device includes ultrasonic sensors for detecting objects around the vehicle, a device for predicting that a motorcycle is approaching the vehicle, and a device for adjusting a detection distance and a detection sensitivity of the ultrasonic sensors. When the predicting means predicts a motorcycle approach, the adjusting device makes the detection distance longer than a normal distance and the detection sensitivity higher than a normal sensitivity. Illuminating devices may be mounted on the vehicle to make the motorcycle passing by visible. A warning may be given to a driver when a motorcycle passing by is actually detected by the sensors. Information regarding the detected motorcycle may be given to other vehicles. According to the present invention, the motorcycle passing by the vehicle is surely and stably detected to thereby avoid any traffic accident with the motorcycle.

摘要： A system wherein management data for managing allowance or unallowance (i.e., prohibition) of copies on a recording medium are recorded, and a time restriction condition, an area limiting condition, a condition for restricting a copy mode, etc. are managed on the basis of the recorded copy management data. When data are copied to different recording media, the copy management data are recorded together with the main data, thereby restricting the reproducing operation of the main data.
