Knowlege in basic mathematical methods of physicsA Fourier transform converts signals from the time g(t) domain to the frequency G(w)domain. In the Fourier domain, it is possible to analyze the signals in the real, absolute, or imaginary planes. In any communication channel some noise is added to the signal. The white noise contains all the frequencies with a uniform power spectrumComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
