ABSTRACT:
Such a digital receiver comprises a digital band-pass filter16for performing digital filtering on digital data DIFof the intermediate frequency, the digital data DIFfrequency-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 filter17for performing digital filtering on digital data DBFoutput from the digital band-pass filter16at a second sampling rate equal to an exponentiation multiple of 2 of the intermediate frequency and outputting the resulting data to a detection circuit18.
