Solution:

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

Solution:

where X(f,T) is the Fourier transform of the signal over a finite interval T. Solution: f_USB = f_c + f_m = 100

2.1 Find the Fourier transform of a rectangular pulse. Solution: f_USB = f_c + f_m = 100

Coherent digital modulation uses a reference carrier signal at the receiver to detect the transmitted signal, while noncoherent digital modulation does not use a reference carrier signal.
