Abstract
A high frequency signal receiving device includes a reference frequency signal generating section operable to generate a reference frequency signal; a high frequency signal processing section operable to obtain a signal of a desired channel from a high frequency signal using the reference frequency signal, the high frequency signal being obtained by receiving a broadcast wave; an analog demodulating section operable to subject the signal of the desired channel to an analog demodulation process; and a digital demodulating section operable to subject the signal of the desired channel to a digital demodulation process using the reference frequency signal.
