고정소수점 필터
고정소수점 필터 설계
DSP System Toolbox™ 및 Fixed-Point Designer™ 기능을 사용하여 고정소수점 신호 처리 필터링 알고리즘을 모델링하고 양자화가 시스템 동작과 성능에 미치는 영향을 분석할 수 있습니다. 고정소수점 연산을 지원하는 DSP System Toolbox System object 목록은 System Objects in DSP System Toolbox that Support Fixed-Point Design 항목을 참조하십시오. 고정소수점 연산을 지원하는 DSP System Toolbox 블록 목록을 보려면 showsignalblockdatatypetable
