: A technique used to encode a message signal onto a carrier wave for transmission. Modulation schemes are critical in telecommunications for efficient and reliable data transfer.

: Basic definitions and properties of signals and systems. This includes continuous-time and discrete-time signals, deterministic and random signals.

Their collaboration produced a textbook that bridges the gap between abstract mathematical formalism and physical engineering intuition. Unlike foreign texts translated into Italian, Teoria dei Segnali was written natively in Italian, capturing the precise nuances needed for Italian exam circuits ( analisi dei circuiti ).

Check if your university library offers a digital lending service. Platforms like Pearson or McGraw-Hill (depending on the publisher) often sell official eBooks with watermarks, which offer the same convenience as a PDF without the legal risk. Furthermore, official university repositories often provide "dispense" (lecture notes) authored by Luise and Vitetta specifically for their courses, which are legally free.

This section rebuilds the foundation of mathematical analysis:

The book is not just another manual; it is a structured course. The typically contains the following core modules, which are critical for any engineering student:
