For undergraduate courses on Signals and Linear Systems.

This book contains a comprehensive set of computer exercises of varying levels of difficulty covering the fundamentals of signals and systems. The exercises require the reader to compare answers they compute in MATLAB® with results and predictions made based on their understanding of the material. The book is compatible with any introductory course or text on signals and systems.

  • NEW - Now based on the latest release of MATLAB Version 12.
  • NEW - Real-world applications and actual data—Including speech processing, financial time series analysis, stabilization of mechanical systems with feedback, communication systems (AM, FM, FDMA, TDMA, SSB, asynchronous demodulation), electrical circuits, FIR and IIR Filter design (frequency sampling, least squares, Butterworth, Parks-McCellan), automobile suspension, image processing, and telephony.

    • Engages the student with concrete problems that reinforce intuition and critical thinking.

  • A large number of problems (about 750) offer flexibility for the instructor.

    • Allows the book to be used every semester without re-using problems.

  • Problems are divided into Basic, Intermediate, and Advanced levels.

    • Ensures mastery of the fundamental tools before exposure to applications and advanced concepts.

  • Ten (10) Tutorial sections.

    • Provides worked examples to expose students to the fundamental conceptual tools and MATLAB functions used in that chapter.

  • Continuous and discrete-time signals and systems are covered.
  • A comprehensive index of topics covered.
  • Exercises can be completed with the student edition of MATLAB.
  • Now based on the latest release of MATLAB Version 12.
  • Real-world applications and actual data—Including speech processing, financial time series analysis, stabilization of mechanical systems with feedback, communication systems (AM, FM, FDMA, TDMA, SSB, asynchronous demodulation), electrical circuits, FIR and IIR Filter design (frequency sampling, least squares, Butterworth, Parks-McCellan), automobile suspension, image processing, and telephony.
