Abstract
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.
Claims13
A selection device comprising:
- an acquisition part which acquires a digital selection signal;
- and
- an output part which outputs a selection signal to each of a plurality of unit cells which can be instructed to output a value 0,
- wherein
- the selection signal instructs an output of a value corresponding to the selection signal to the unit cell,
- the total of a value of outputs instructed by the selection signals output to the plurality of unit cells is a value determined according to the digital selection signal, and
- when the output corresponding to the digital selection signal is a value 0, a unit cell exists which is output with a selection signal which instructs an output of a value N which is not 0.
