Sorgenti e destinazioni

Segnali e sequenze di input e di output e formati di file IO

Generare i dati sorgente del segnale e il rumore per simulare i collegamenti della comunicazione. Visualizzare e analizzare la prestazione della simulazione del sistema di comunicazione.

I formati di file supportati per l'elaborazione dei segnali acquisiti comprendono segnali binari in banda base e file in formato NI™ technical data management solution (TDMS). È possibile raccogliere i dati in tabelle o orari leggendo i file TDMS singolarmente o leggendo raccolte di file TDMS simultaneamente.
