Brief summary
The book focuses on the mathematical description of typical signals in Communications Engineering, which can be done alternatively in the time or frequency domain:
- Components of communication systems and classification of different signals.
- The Fourier series for the description of periodic signals with the special case »harmonic oscillation« and the limiting case »direct current signal«.
- The laws of the Fourier transform for describing aperiodic $($impulsive$)$ signals and their spectra; first and second Fourier integral.
- Peculiarities of band-pass signals and their description by the analytical signal and the equivalent low-pass signal.
- Discrete Fourier transform for the description of discrete-time signals; application for spectral analysis; FFT as an efficient computer implementation.
The spectral transforms $($Laplace transform, z-transform, Hilbert transform$)$ applicable exclusively to causal signals and systems are not treated in this book. Here we refer to the book »Linear and Time Invariant Systems«.
⇒ First a »content overview« on the basis of the »five main chapters« with a total of »19 individual chapters« and »127 sections«.
