Abstract
A receiver accepts a digital signal having an upper side digital signal located in a higher frequency range on a frequency axis than an analog signal, and a lower side digital signal located in a lower frequency range on the frequency axis than the analog signal. A BPF () allows the analog signal to pass therethrough and a BPF () allows the analog signal and the digital signal to pass therethrough. BPFs () and () accept the output of the BPF () and output the upper side digital signal and the lower side digital signal, respectively. A digital receive level determining unit () and a selection SW () select either of the outputs of the BPFs () and () according to the receive levels of the upper side digital signal and the lower side digital signal, and output the selected output as a selected signal. The receiver then demodulates this selected signal.
