Indica quines de les afirmacions són correctes respecte a la transmissió en banda estreta

En un entorn on la dispersió temporal és de 17 ns, determina la màxima taxa en Kbits per segon que pot transmetre en condicions de banda estreta en aquest canal un sistema que utilitza una modulació binària. Assumeix que podem considerar condicions de banda estreta si la dispersió temporal és inferior al 10% del temps de símbol (dona la resposta amb 1 decimal).

En un entorn on les pèrdues per esvaïments deguts a obstacles estan modelades per una distribució normal amb desviació estàndard de 6 dB.

Quin valor de pèrdues podem afirmar amb seguretat que els esvaïments provocats pels obstacles només superaran un 2.2% del temps?
