E/S radio

Émettre et recevoir des signaux RF réels

Lors de l’émission ou de la réception de signaux RF réels, utilisez les propriétés et techniques d’E/S pour effectuer des E/S monocanaux et multicanaux, détecter les échantillons perdus, appliquer une mise en mémoire tampon en mode rafale et émettre une forme d’onde de manière répétée.
