4.1 An FM signal has a carrier frequency of 100 MHz and a modulating signal of 10 kHz. Calculate the frequency deviation.
6.1 A transmission line has a characteristic impedance of 50 Ω and a length of 100 m. Calculate the propagation constant.
Solution:
Solution:
2.1 Find the Fourier transform of a rectangular pulse.
Solution:
where A is the amplitude, τ is the pulse duration, and sinc is the sinc function. Calculate the propagation constant
1.2 What are the advantages of using electronic communication systems?
5.1 Explain the difference between coherent and noncoherent digital modulation.
This draft report provides solutions to selected problems in the fourth edition of "Sistemas de Comunicaciones Electrónicas" by Wayne Tomasi. The solutions cover various topics in electronic communication systems, including signals and systems, amplitude modulation, angle modulation, digital modulation, and transmission lines and waveguides. including signals and systems
The Fourier transform of a rectangular pulse is given by:
2.2 Determine the power spectral density of a random signal.
where α is the attenuation constant and β is the phase constant. τ is the pulse duration
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.
