Book Contents
The book is structured into several chapters, each progressively building upon key concepts. Below is an overview of its main sections:
1. Introduction to Signals and Systems
The opening chapter provides a foundational understanding of signals and systems, introducing key terms such as deterministic and random signals, periodic and aperiodic signals, and the classification of systems. It also explores the mathematical representation of signals and the significance of system properties like linearity, time-invariance, and causality.
2. Linear Time-Invariant (LTI) Systems
This section delves into the behavior of LTI systems, exploring impulse response functions and convolution operations. MATLAB demonstrations enable readers to visualize how systems respond to different input signals, offering an intuitive grasp of concepts such as system stability and frequency response.
3. Laplace Transform and System Analysis
The Laplace transform plays a crucial role in signal and system analysis, particularly in solving differential equations for system modeling. This chapter introduces Laplace transform techniques and applies them to system characterization, transfer functions, and circuit analysis.
4. Fourier Transform and Spectral Analysis
Frequency-domain analysis is an essential topic covered extensively in this book. The Fourier transform helps in understanding signal properties such as bandwidth, filtering, and spectral content. MATLAB implementations provide practical insights into spectral decomposition and signal reconstruction.
5. Z-Transform and Discrete-Time Systems
For discrete-time systems, the Z-transform proves invaluable in system analysis. This chapter discusses stability criteria, pole-zero analysis, and the behavior of discrete-time filters. It also includes MATLAB examples illustrating signal processing applications.
6. Practical Applications Using MATLAB
MATLAB is a core component of this textbook, with dedicated sections demonstrating how to implement signal transformations, design filters, analyze system responses, and perform real-world signal processing tasks. Practical examples include audio processing, image filtering, and communication system analysis.
