5. Bandlimited white noise N(t) has spectral density S,(f) = 10° V7/Hz over the
frequency range -100 kHz to 100 kHz.
a) Whatis the mms value of the noise?
b) Find R,,(t). At what spacings are n(t) and n(t+t) uncorrelated?
6. The multitone modulating signal m(t) = K(2cos(m,,t) + cos(2m,,t) + 3 cos(Sm,,t)) is the
input to an AM system.
a) Find K so that mit) is properly normalized (i.e, to prevent overmodulation).
b) Plot the frequency spectrum of the transmitted signal s(t).
c) Calculate Poy /P ier ANd PrariodProta: (P represents power.)
