Unformatted text preview: gnal consists of a single tone with frequency
fm = 1000 Hz = 1 kHz.
a. The peak phase deviation is 5 radians.
b. The instantaneous frequency deviation ∆ω (t) = d
dt θ (t) = 104 π cos(2π 1000t) s−1 . c. The peak frequency deviation, ∆fmax , is 5 kHz.
d. According to Carson’s rule, the bandwidth is BW = 2(fm + ∆fmax ) = 2(1 + 5) kHz = 12 kHz.
e. The spectrum of s(t) will consist of delta functions located at fc ± nfm . The ﬁlter will allow the
carrier component and the ﬁrst three sidebands to pass, i.e. the delta functions corresponding...
