    • A radio broadcast reception device includes a radio DSP which performs a signal process on analog radio audio by using a radio DSP parameter, an audio DSP which performs a signal process on digital radio audio by using an audio DSP parameter, a controlling section which outputs a switching signal in accordance with the quality of a received radio wave of a digital radio broadcast, and a blending section which switches between an output of the radio DSP and an output of the audio DSP. In accordance with the switching signal, while maintaining an output level constant, the blending section gradually switches between the output of the radio DSP and the output of the audio DSP, during a predetermined time period.
    • 无线电广播接收装置包括通过使用无线DSP参数对模拟无线电音频进行信号处理的无线电DSP,通过使用音频DSP参数对数字无线电音频执行信号处理的音频DSP,控制部分,其输出 根据数字无线电广播的接收无线电波的质量,以及在无线电DSP的输出和音频DSP的输出之间切换的混合部分的切换信号。 根据切换信号,在保持输出电平恒定的同时,在预定时间段期间,混合部分在无线电DSP的输出和音频DSP的输出之间逐渐切换。
