The author begins by reviewing the theory of representation in linear algebra, emphasizing that vectors are represented by different coordinates when the basis is changed, and that the basis of eigenvectors is special because it diagonalizes the operator. Thus, in each step of the theory of representation of signals and systems, the author shows the analogous step in linear algebra. With such an approach, students can easily understand that signals are analogous to vectors, that systems are analogous to matrices, and that Fourier transforms are a change to the basis that diagonalizes LTI operators. \u003c\/p\u003e\n\u003cp\u003eThe text emphasizes the key concepts in the analysis of linear and time invariant systems, demonstrating both the algebraic and physical meaning of Fourier transforms. The text carefully connects the most important transforms (Fourier series, Discrete Time Fourier Transform, Discrete Fourier Transforms, Laplace and z-transforms), emphasizing their relationships and motivations. The continuous and discrete time domains are neatly connected, and the students are shown step-by-step how to use the fft function, using simple examples.  \u003c\/p\u003e\n\u003cp\u003eIncorporating learning objectives and problems, and supported with simple Matlab codes to illustrate concepts, the text presents to students the foundations to allow the reader to pursue more advanced topics in later courses.  \u003c\/p\u003e\n\u003cp\u003eDeveloped from lecture notes already tested with more than 600 students over six years, \u003ci\u003eEssentials of Signals and Systems \u003c\/i\u003ecovers sample topics such as: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBasic concepts of linear algebra that are pertinent to signals and systems. \u003c\/li\u003e \u003cli\u003eTheory of representation of signals, with an emphasis on the notion of Fourier transforms as a change of basis, and on their physical meaning. \u003c\/li\u003e \u003cli\u003eTheory of representation of linear and time invariant systems, emphasizing the role of Fourier transforms as a change to the basis of eigenvectors, and the physical meaning of the impulse and frequency responses. \u003c\/li\u003e \u003cli\u003eWhat signals and systems have to do with phasors and impedances, and the basics of filter design.\u003c\/li\u003e \u003cli\u003eThe Laplace transform as an extension of Fourier transforms.\u003c\/li\u003e \u003cli\u003eDiscrete signals and systems, the sampling theorem, the Discrete Time Fourier Transform (DTFT), the Discrete Fourier Transform (DFT), and how to use the fast fourier transform (fft).\u003c\/li\u003e \u003cli\u003eThe z-transform as an extension of the Discrete Time Fourier Transform.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003ci\u003eEssentials of Signals and Systems \u003c\/i\u003eis an immensely helpful textbook on the subject for undergraduate students of electrical and computer engineering.
