6.1 A transmission line has a characteristic impedance of 50 Ω and a length of 100 m. Calculate the propagation constant.

Solution:

F(ω) = A * τ * sinc(ωτ/2)

The sideband frequencies are given by:

f_USB = f_c + f_m = 100 kHz + 5 kHz = 105 kHz f_LSB = f_c - f_m = 100 kHz - 5 kHz = 95 kHz

2.2 Determine the power spectral density of a random signal.

where α is the attenuation constant and β is the phase constant.
