DEMODULATION DEVICE, RECEPTION DEVICE, AND DEMODULATION METHOD

摘要

It is possible to prevent lowering of reception performance caused by a higher harmonic component of a clock used for demodulation. A demodulation device includes: a tuner which multiplies a reception signal by a signal of a frequency corresponding to that of a desired signal contained in the reception signal so as to perform a frequency conversion and output the obtained frequency-converted signal; and a demodulation unit which demodulates the frequency-converted signal so as to generate a demodulated signal. The demodulation unit operates according to a master clock of a frequency corresponding to that of the desired signal.
