The frequency deviation is given by:

Solution:

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. The frequency deviation is given by: Solution: Coherent

where A is the amplitude, τ is the pulse duration, and sinc is the sinc function.

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

2.2 Determine the power spectral density of a random signal.

where α is the attenuation constant and β is the phase constant. The frequency deviation is given by: Solution: Coherent

Solution:
