    摘要： An FM/FMX stereophonic receiver is capable of receiving an FM or an FMX stereophonic broadcast signal. The FM stereophonic broadcast signal includes a stereo sum signal and stereo difference signal, whereas the FMX stereophonic broadcast signal further includes a compressed stereo difference signal and an FMX ID signal indicating the FMX stereophonic broadcast signal. The FM/FMX stereophonic receiver has a stereo demodulator for receiving said broadcast signal and for producing left and right stereo signals, a detector for detecting the field strength of the receiving signal, and a noise reducer, which may be a circuit for changing the mode from stereophonic mode to monaural mode or a high cut circuit for attenuating the signals of high frequency region, for reducing noise signals contained in the left and right stereo signals. The FM/FMX stereophonic receiver further has a detector for detecting the FMX ID signal and a disabling circuit for disabling the noise reducer when the FMX ID signal is detected by the detector. Instead of the disabling circuit, a timing control circuit may be provided for changing the timing at which the noise reducer starts to activate in response to the detection of the FMX ID signal.

    摘要： An improved FMX sterophonic broadcast receiver provided with countermeasures against transient noises, which includes a level detection circuit for detecting level of a detected stereo difference signal, and a level control circuit for controlling level of an expanded stereo difference signal according to an output signal of the level detection circuit. By the above arrangement of the present invention, since it is so arranged to cause the level control circuit to function when the degree of modulation becomes large so as to control the level of the stereo difference signal to be low, a level difference is produced between the stereo sum signal and the stereo difference signal for deterioration of the stereo separation degree upon matrixing at a matrix circuit for reduction of noises accordingly.

    摘要： An FMX stereophonic receiver receives an FMX stereophonic broadcast signal which includes a stereo sum signal, an uncompressed stereo difference signal, and a compressed stereo difference signal which is formed by modulating the uncompressed stereo difference signal by a quadrature modulation and being compressed. The FMX stereophonic receiver includes an FM detector for producing an FM detection signal including a stereo pilot signal, a PLL circuit for producing a signal which is in a synchronized relationship with the stereo pilot signal included in the FM detection signal, a synchronous detection circuit for receiving the FM detection signal and for producing the uncompressed stereo difference signal in accordance with the signal produced from the PLL circuit, a quadrature detection circuit for receiving the FM detection signal and for producing the compressed stereo difference signal in accordance with the signal produced from the PLL circuit, and a phase shifting means for shifting the phase of at least one of the FM detection signal applied to the PLL circuit and the FM detection signal applied to the detection circuits so as to correct the phase difference between the synchronous detection signal and the signal to be detected.

    摘要： A television receiver includes a volume control circuit (4) for controlling levels of sound signals corresponding to a left channel, a right channel, a center channel and a surround channel and speakers (6 to 10) corresponding to these channels. The television receiver further comprises a test tone circuit (11; 18), a microcomputer (14) and a character display circuit (16).

    摘要： A PLL circuit comprises a variable frequency divider (7) for frequency-dividing a signal having a reference frequency f.sub.1 with a frequency dividing ratio n.sub.1 or n.sub.2, a fixed frequency divider (8) for further frequency-dividing an output of the variable frequency divider with a frequency dividing ratio n.sub.0, to generate a first output signal and a second output signal which is out of phase by 90.degree. from the first output signal, multiplier (10) for multiplying an input signal by the second output signal, a comparator (11) for comparing an output of the multiplier with a predetermined reference voltage, and a D-type flip-flop (12) receiving as a D input an output of the comparator and receiving as a clock input the first output signal, an output of the D-type flip-flop (12) being applied to the variable frequency divider (7). When the second output signal leads the input signal by 90.degree. or more, the output of the D-type flip-flop (12) attains an "L" level, so that the large frequency dividing ratio n.sub.2 is selected. On the other hand, when the second output signal lags the input signal by 90.degree. or more, the output of the D-type flip-flop (12) attains an "H" level, so that the small frequency dividing ratio n.sub.1 is selected.

    摘要： In a net boot type thin client system, bottle necks concentrate on specific steps in a previously downloading method and an on-demand downloading method so as to hinder high-speed operation. Specifically, a previously file acquiring section for acquiring a file before the OS operates, an on-demand file acquiring section for acquiring a file while the OS operates, and a file determining section for determining whether or not a file is used in a high frequency. A high use-frequency file is downloaded before an OS operates and a low use-frequency file is downloaded while the OS operates.
