Abstract
A receiving apparatus includes: a signal-level detecting unit detecting a signal level of an input signal; a first signal-level converting unit including amplifiers, capturing the input signal and converting a signal level of the input signal; a switching unit switching an output of a converted level signal; a switching control unit selecting a specific amplifier and controlling the switching unit to select an output signal from the selected amplifier; a band-pass filter allowing only a predetermined frequency hand in the switched signal to pass; a second signal-level converting unit converting a signal level of an output signal from the amplifier into a predetermined signal level at which S/N of a mixer is maximized; the mixer mixing the converted signal passed through the band-pass filter, and an oscillation signal to generate an intermediate frequency signal; and a demodulating unit demodulating the intermediate frequency signal.
