    • A radiofrequency signal is converted to an intermediate frequency signal by a tuner, which is amplified by a variable gain amplifier. The so-amplified signal is converted into a digital signal by an ADC, which is supplied to an FFT, where it is separated into signals set every carrier, followed by being supplied to equalizers different in characteristic. The digital signal outputted from the ADC is further supplied to a level converting circuit from which a control signal is generated. The control signal is supplied to a DAC and a Doppler frequency detector. The DAC generates a gain control signal and supplies the same to the variable gain amplifier. The Doppler frequency detector outputs a frequency component of the control signal as a Doppler detection signal. The Doppler detection signal is compared with a threshold value by a comparator. A selector selects one of signals outputted from the equalizers, in accordance with a select signal indicative of the result of comparison.
    • 射频信号由调谐器转换成中频信号,该调谐器由可变增益放大器放大。 被放大的信号被ADC转换成数字信号,ADC被提供给FFT,其中被分离成每个载波设置的信号,随后被提供给不同特性的均衡器。 从ADC输出的数字信号进一步提供给产生控制信号的电平转换电路。 控制信号被提供给DAC和多普勒频率检测器。 DAC产生增益控制信号并将其提供给可变增益放大器。 多普勒频率检测器输出控制信号的频率分量作为多普勒检测信号。 通过比较器将多普勒检测信号与阈值进行比较。 选择器根据表示比较结果的选择信号来选择从均衡器输出的信号之一。
