    • A trouble determining apparatus for a chopper type DC boosting circuit capable of determining whether or not a switching device is in trouble securely and quickly and when the switching circuit is in trouble, preventing other circuit from being in a trouble. Upon determining a short-circuit trouble of a transistor Q, a boosting circuit control unit 22 is turned OFF a power relay RL and then determines whether or not a voltage VP1 of a connecting point P1 rises over a first set voltage VS1 by the time when a first predetermined time t1 elapses since an ignition switch IG is turned ON with the transistor Q set to OFF. Upon determining an open trouble of the transistor Q, the boosting circuit control unit 22 determines whether or not the voltage VP1 of the connecting point P1 falls below a second set voltage by the time when a second predetermined time t2 elapses since the transistor Q is turned ON with the power relay RL set to OFF and whether or not the voltage VP1 falls from a state before the transistor Q is turned ON by more than a third set voltage.

    • A tuning circuit's bandwidth is maintained almost constant throughout a UHF low to high band range so as to prevent interference by a neighboring channel, particularly in receiving high band television signals, and also to improve NF in receiving low band television signals, eliminating a difference in NF between channels. To realize this, a UHF tuner comprises: a UHF tuning circuit which has a varactor diode first and second inductance elements serially interconnected and connected in parallel with the varactor diode, where the varactor diode 11a varies a tuning frequency within a prescribed frequency range in the UHF band; and impedance means which is serially inserted between an input terminal and the junction of the two inductance elements, where the impedance by the impedance means increases as a frequency increases within the prescribed frequency range in the UHF band.

    • In a demodulator for demodulating a BPSK modulated signal, demodulation performance degradation caused by analog circuits such as fabrication variation is suppressed, and furthermore, frequency variation in the BPSK modulated signal is followed by the demodulator. A multiplication circuit 105 multiplies a carrier, generated from a BPSK modulated signal by a carrier information extraction circuit 101 and a carrier generation circuit 102, by a digital BPSK modulated signal obtained by digitizing the BPSK modulated signal by an A/D converter 104 via a LPF 103. A carrier period integration circuit 106 integrates the multiplication result with respect to the period of the carrier, and the integration result is then binarized in a discriminator 107, thereby realizing demodulation.
