ABSTRACT:
A frequency conversion apparatus comprising a sampling circuit for receiving a first intermediate frequency signal extracted from an input signal and having a predetermined intermediate frequency and a predetermined band width and sampling the first intermediate frequency signal in accordance with a predetermined sampling frequency signal, to output a second intermediate frequency signal, and a sampling signal generator for outputting the sampling frequency signal to the sampling circuit, the sampling frequency signal having a frequency determined so that an integer multiple of not less than three times the sampling frequency is outside a frequency range of the input signal.
