摘要： A reception circuit 10 for receiving an analog broadcast and outputting an audio signal based on the analog broadcast is provided with a digital demodulation circuit 28 for digitally demodulating an intermediate frequency signal obtained in the reception circuit 10 at the reception time of the digital broadcast and outputting the audio signal based on the digital broadcast, a control circuit 34 for controlling the operating power source voltage of the digital demodulation circuit 28, a detection circuit 31 for detecting the reception of the analog broadcast, and a detection circuit 32 for detecting the reception of the digital broadcast. Only when the detection circuit 31 detects the broadcast wave signal of the analog broadcast at the station-selection time and the detection circuit 32 detects the broadcast wave signal of the digital broadcast, is the operating power source voltage supplied to the digital demodulation circuit 28 by the control circuit 34.

摘要： An amplifier in which a current mirror circuit 53 is formed of a transistor Q25 on the input side and a transistor Q26 on the output side. The base-emitter junction area of the transistor Q26 is set to be N (N > 1) times as large as that of the transistor Q25. A parallel circuit of a resistor R25 and a capacitor C25 is connected between the base of the transistor Q25 and its bias point Q27. A resistor R26 is connected between the base of the transistor Q26 and the bias point Q27. The resistance value of the resistor R25 is set to be virtually N times as large as the resistance value of the resistor R26. When an input current i25 is supplied to the transistor Q25, an output current i26, which is N times as large as the input current, is obtained from the transistor Q26 on the output side, whereas the output current i26 is held lower than N times of the input current i25 when the frequency of the input current is high

摘要： In an automatic gain control unit, the gain of a voltage-controlled amplifier (VCA) (25) is regulated with a closed-loop control circuit. The time constant of the control circuit is varied dependent on the magnitude (31) of the VCA output signal. As long as the magnitude (31) of the VCA output signal is small, the gain is slowly adjusted. In case the-magnitude (31) of the VCA becomes so large that saturation of the analog-digital converter (28) might occur, the time constant of the control circuit is decreased, in order to allow for a quick adjustment of the amplifier's gain.
摘要翻译：在自动增益控制单元中，通过闭环控制电路调节压控放大器（VCA）（25）的增益。控制电路的时间常数取决于VCA输出信号的幅度（31）而变化。只要VCA输出信号的幅度（31）小，增益就缓慢调整。在VCA的幅度（31）变得如此大以至可能发生模拟数字转换器（28）的饱和的情况下，控制电路的时间常数减小，以便允许快速调整放大器的增益。
