<P>PROBLEM TO BE SOLVED: To provide an on-vehicle receiver capable of eliminating alteration of sound quality due to a difference in frequency characteristics when switching between digital radio broadcasting and analog radio broadcasting. <P>SOLUTION: An on-vehicle receiver 10 which receives simultaneous broadcasting includes: a radio DSP15 that performs signal processing on audio signals included in the analog radio broadcasting to output analog radio audio signals; a frequency comparison section 19 that outputs a control signal according to a difference in frequency characteristics between a digital radio audio signal output from a digital radio demodulation section 12 and an analog radio audio signal output from the radio DSP15; and an audio DSP16 that generates a pseudo high frequency audio signal according to the control signal output from the frequency comparison section 19 and adds the pseudo high frequency audio signal to the analog radio audio signal output from the radio DSP15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
