Abstract: A subtraction section subtracts a first signal from a second signal as a harmonic signal and outputs a third signal as a subtraction result. A first conversion section converts the third signal into a digital signal of predetermined frequency different from a frequency of the second signal. A second conversion section converts the digital signal into an analog signal of a frequency nearly equal to the frequency of the second signal and supplies the analog signal as the first signal to the subtraction section. The second conversion section includes a plurality of conversion elements, a filter to calculate a number of use of each of the plurality of conversion elements, and a selector to select, the conversion elements having a lower value of the number of use. The number of conversion elements selected corresponds to the value of the digital signal.

Abstract: A sampling frequency conversion apparatus having N (where N is an integer, which is two or more) sampling conversion means serially connected, each of the N sampling frequency conversion means comprising a first digital filter for outputting a signal with longer bit length than that of an input signal, and first sampling means for sampling a signal which is output from the digital filter at a sampling frequency, the sampling frequency decreasing as the stage of the sampling frequency conversion means becomes later. Thus, the earlier stages which should be operated at a high speed, the bit length of signals becomes short. In the later stages where the bit length becomes long, the sampling frequencies are decreased. Consequently, the apparatus can be operated at a high speed and constructed at a low cost.
