Such a digital receiver comprises a digital band-pass filter 16 for performing digital filtering on digital data DIF of the intermediate frequency, the digital data DIF frequency-converted by a frequency converter and undergone analog-to-digital conversion, at a first sampling rate equal to an exponentiation multiple of 2 of the intermediate frequency, and an interpolation filter 17 for performing digital filtering on digital data DBF output from the digital band-pass filter 16 at a second sampling rate equal to an exponentiation multiple of 2 of the intermediate frequency and outputting the resulting data to a detection circuit 18.
