Description
アナログ高域通過フィルターが不要なため、精密部品とそれの時間消費パラメータ整合が取り除かれる。
データ処理が、完全にデジタル式で実行される。
導出が大地電位で実行されるので、測定データがデジタル式減算の後、単一極である。
異なるゲイン要素とサンプリング速度で、異なる起源の生体信号を同時に取得することが可能である。
データは、従来のシステムのように時多重方式により取得されないが、モジュラー構造により、同時でも、互いに完全に独立ででも、スキャン可能である。
アナログ・デジタル変換が、その小さい構造サイズにより信号源のすぐ近くで実行され得る。従って、アナログ信号経路がとても短いので干渉が減少し、ハードウエアのアナログ部の導体ループを介する誘導により繋がれた干渉が防がれる。従来の増幅器は差動入力電圧または電流として存在し、有効信号によって増幅されるので、誘導により繋がれた干渉と有効信号を分けることができない。
