INTRODUCTION TO DIGITAL FILTERS
1 INTRODUCTION TO DIGITAL FILTERS Analog and digital filters In signal processing the function of a filteris to remove unwanted parts of the signal such as random noise or to extract useful parts of the signal such as the components lying within a certain frequency range The following block diagram illustrates the basic idea |
What is digital filter classification?
Filter classification. Digital filters can be convolution implemented (also called in finite impulse or FIR ) and response recur by (also ion infinite called response or IIR ). Filters carried out by performance than filters using recursion, The next six chapters describe digital Table 14-1.
What are digital filters used for?
Filters can be used to shape the signal spectrum in a desired way or to perform mathematical operations such as differentiation and integration. In what follows you will learn some practical concepts that will ease the use of filters when you need them. This example focuses on applications of digital filters rather than on their design.
