Smorzatori, commutatori e contatori
R2026aConvertire le velocità dei segnali e le dimensioni dei frame in Simulink® utilizzando blocchi di smorzamento dei frame, quali i blocchi Buffer, Unbuffer e Delay Line. Implementare smorzatori FIFO e LIFO utilizzando i blocchi Queue, Stack in Simulink e l'oggetto dsp.AsyncBuffer in MATLAB®. È inoltre possibile contare gli eventi, rilevare i fronti ed eseguire azioni al verificarsi degli eventi utilizzando i blocchi commutatori e contatori in DSP System Toolbox™.
