신호 생성

샘플 기반 및 프레임 기반 처리를 위한 신호 만들기

DSP System Toolbox™의 소스 블록과 System object를 사용하여 샘플 기반 처리와 프레임 기반 처리를 위한 신호를 생성할 수 있습니다.

Colored Noise 블록 및 Sine Wave 블록과 같은 소스 블록은 미리 정의된 알고리즘을 사용하여 신호를 생성합니다. 이러한 블록 대부분은 생성하는 각 프레임(열)의 샘플 수를 제어할 수 있습니다. 이러한 소스 블록을 사용하여 신호를 생성하는 방법을 보여주는 예제는 Create Signals for Sample-Based Processing 항목과 Create Signals for Frame-Based Processing 항목을 참조하십시오.
