CHAPTER 7 Introduction to Digital Signal Processing
7.1 Introduction
The processing of analogue electrical signals and digital data from one form to another is fundamental to many electronic circuits and systems. Both analogue (voltage and current) signals and digital (logic value) data can be processed by many types of circuits, and the task of finding the right design is a sometimes confusing but normal part of the design process. It depends on identifying the benefits and limitations of the possible implementations to select the most appropriate solution for the particular scenario. Initial concerns are:
• Is the input analogue or digital?
• Is the output analogue or digital?
• Will signal processing use analogue or digital techniques? ...
