Buffer, Schalter und Zähler
R2026aMit Frame-Rebuffering-Blöcken wie Buffer, Unbuffer und Delay Line können Sie in Simulink® Signalraten und Framegrößen konvertieren. Implementieren Sie mithilfe der Blöcke Queue und Stack in Simulink und dem dsp.AsyncBuffer-Objekt in MATLAB® FIFO- und LIFO-Buffer. Zudem können Sie mit den Switch- und Counter-Blöcken in DSP System Toolbox™ Ereignisse zählen, Ränder erkennen und bei Ereignissen Aktionen ausführen.
