摘要： A selection device includes an acquisition part to acquire digital selection signals, and an output part to output selection signals to respective unit cells, each unit cell capable of being commanded to output the value zero. In the selection device, each selection signal is to command the unit cell to output a value corresponding to that selection signal; the sum of the values to be output as commanded by the respective selection signals, which are output to the respective unit cells, is a value determined in association with the digital selection signal; and if the output corresponding to the digital selection signal is the value zero, then selection signals each commanding to output a non-zero value (N) are output to some of the unit cells.

摘要： 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.
