2.1 Find the Fourier transform of a rectangular pulse.

Solution:

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

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.

γ = α + jβ
