Signal Processing Toolbox

Signal Processing Basics

This chapter describes how to begin using MATLAB and the Signal Processing Toolbox for your signal processing applications. It assumes a basic knowledge and understanding of signals and systems, including such topics as filter and linear system theory and basic Fourier analysis. The chapter covers the following topics:

• Signal Processing Toolbox Central Features
• Representing Signals
• Waveform Generation: Time Vectors and Sinusoids
• Working with Data
• Filter Implementation and Analysis
• The filter Function
• Other Functions for Filtering
• Impulse Response
• Frequency Response
• Zero-Pole Analysis
• Linear System Models
• Discrete Fourier Transform
• Selected Bibliography

Many examples throughout the chapter demonstrate how to apply toolbox functions. If you are not already familiar with the signal processing capabilities in MATLAB, use this chapter in conjunction with the software to try examples and learn about the powerful features available to you.
