t (second)
a.) (5 pts) if $m(t)$ is frequency modulated by a carrier with frequency $10^6$ Hz and
$K_f = 6$ Hz, what are:
i.) the instantaneous frequency (in unit of Hz) of the modulated signal?
ii.) the frequency deviation (in unit of Hz) of the modulated signal?
iii.) the bandwidth (in unit of Hz) of the modulated signal?
b.) (5 pts) if $m(t)$ is phase modulated by a carrier with frequency $10^6$ Hz and $K_p =$
$4\pi$ Hz, what are:
iv.) the instantaneous frequency (in unit of Hz) of the modulated signal?
v.) the frequency deviation (in unit of Hz) of the modulated signal?
vi.) the bandwidth (in unit of Hz) of the modulated signal?
