ABSTRACT:
A signal selecting circuit is disclosed which outputs a first and a second digital signals by converting a first and a second analog signals into digital signals, the first and the second analog signals being the same or different signals selected from a plurality of analog signals, the signal selecting circuit comprising: an analog signal selection circuit that, based on an analog selection signal, selects the first and the second analog signals from the plurality of analog signals; a first AD converter that converts the first analog signal outputted from the analog signal selection circuit into a third digital signal to output the third digital signal; a second AD converter that converts the second analog signal outputted from the analog signal selection circuit into a fourth digital signal to output the fourth digital signal; a digital signal selection circuit that, based on a digital signal, selectively outputs one or both of the third and the fourth digital signals as the first and the second digital signals; and a control circuit that, based on an output selection signal for selecting the first and the second digital signals, outputs the analog selection signal and the digital selection signal.
