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： There is provided a receiver equipped with a first and a second mixer circuits for performing the frequency conversion of a received signal into two intermediate-frequency signals, phases of which are orthogonal to each other, by means of two local oscillation signals, and a plurality of filter circuits for taking the intermediate-frequency signals out of the output signals of the first and the second mixer circuits. The receiver is further equipped with a demodulation circuit for taking a signal indicating broadcast contents of an analog broadcast or a digital broadcast out of the intermediate-frequency signals taken out by the filter circuits. The frequencies of the local oscillation signals are made to be a frequency apart from the carried frequency of the received signal by the intermediate frequency of the intermediate-frequency signals at a time of receiving the analog broadcast, and the frequency of the local oscillation signals are made to be a frequency equal to the center frequency of the received signal at a time of receiving the digital broadcast.

摘要： In an SRPP circuit, a transistor Q11 has a collector connected to a power supply terminal T13 through a resistor R11 and an emitter connected to the collector of a transistor Q12 having the same polarity as that of the transistor Q11. The emitter of the transistor Q12 is connected to the ground. The collector of the transistor Q11 is connected to the emitter of a transistor Q13 having the polarity opposite to that of the transistor Q11, and the collector of the transistor Q13 is connected to the base of the transistor Q12. A bias voltage V13 is applied to the base of the transistor Q13. An input signal Vin is supplied to the base of the transistor Q11 to extract an output signal from a node between the emitter of the transistor Q11 and the collector of the transistor Q12.
