Author Description

This two-volume text is intended for the two-semester Signals and Systems course taught in many Electrical Engineering Departments. It treats deterministic signals and adds random signals without using statistics. Instead, correlation, second-order convolution, spectral density functions, along with traditional first-order convolution and transforms are introduced in a natural way.Continuous-time and discrete-time systems in both the time domain and frequency domain are treated. Chapters 1 through 5 in this volume introduce continuous- and discrete-time signals, basic signal operations, correlation, random signals, and discrete-time systems. The remainder of this volume concentrates on continuous-time signals and systems (Fourier and Laplace transforms.) Two main topics occupy Volume 2, discrete-time systems and filter design. I know of no better way to consolidate the topics in this text than filter design. All topics are used in a meaningful way and students gain a better understanding of the role of these topics.Several features are unique to this two-part text:1. The relation between the autocorrelation and spectral density functions is introduced in a simple way and expanded throughout the text.2. Both the impulse response and transfer function are derived from the linear time-invariant (LTI) properties. Chapter 6 introduces linearity and time-invariance. Chapter 7 illustrates application of the LTI properties to find the response to an arbitrary input signal from knowledge of one input-output pair. Chapters 8 and 9 then complete this picture by relating the impulse response and transfer function to the LTI properties.3. Phasors are introduced in Chap. 2 of Volume 1. This concept is expanded in Chap. 22 of Volume 2 to present a unique view of all four forms of the Fourier transform.4. This text is user friendly. It lists the learning objectives for each chapter and follows up with a self-test for each objective.5. A unique procedure for designing templates (mat
