Introduction to the
Signal Processing Toolbox

Description

The Signal Processing Toolbox contains tools to help you do digital signal processing (DSP). DSP is the process by which real-world phenomena such as sound and light are analyzed, manipulated, and created using a digital computer.

Thus signal processing permits computers to interact with the world, and ultimately governs the exchange of information from one kind of signal to another. The MATLAB environment is ideal for doing DSP because digital signals are MATLAB's most natural data type.

A modest Halloween treat.
