| description | To provide an analog-digital conversion device or the like capable of reducing quantization noise caused by analog-digital conversion.SOLUTION: An analog-digital conversion device includes an analog calculation part for performing analog calculation of M or more times corresponding to a read code matrix of M analog signal with M being a natural number of two or more, an analog-digital conversion part for performing analog-digital conversion of M or more pieces of analog information as a result of M or more analog calculations and outputting M or more digital signals, and a decoding calculation part for performing decoding calculation using a decode/code matrix corresponding to the read code matrix and including two or more components with each vector different from zero to the M or more digital signals. The analog calculation part is configured to be able to use all of the M analog signals in each of the M or more analog calculations, and the read code matrix and the decoding code matrix are set so as to reduce quantization noise caused by the analog-digital conversion.SELECTED DRAWING: Figure 1
【課題】アナログ－デジタル変換で生じる量子化ノイズを低減することができるアナログ－デジタル変換装置等を提供する。【解決手段】アナログ－デジタル変換装置は、Ｍは２以上の自然数であるものとして、Ｍ個のアナログ信号に対して、読出符号行列に対応するＭ回以上のアナログ演算を行うアナログ演算部と、Ｍ回以上のアナログ演算の結果としてのＭ個以上のアナログ情報をアナログ－デジタル変換し、Ｍ個以上のデジタル信号を出力するアナログ－デジタル変換部と、Ｍ個以上のデジタル信号に対して、読出符号行列に対応しかつ各行ベクトルが０とは異なる２個以上の成分を含む復号符号行列を用いた復号演算を行う復号演算部と、を備え、アナログ演算部は、Ｍ回以上のアナログ演算のそれぞれにおいて、Ｍ個のアナログ信号の全てを利用し得るように構成されており、読出符号行列および復号符号行列は、アナログ－デジタル変換で生じる量子化ノイズを低減するように設定されている。【選択図】図１ |
