Signal models and linear systems

Volker Pohl, Holger Boche

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Nowadays, signal processing uses almost exclusively digital techniques. The majority of applications such as communications, television, speech and image processing, radar, sonar, to name just some, are based on digital signal processing. The major advantage of digital methods over analog ones is the availability of high-speed digital computers at low costs which allow for very efficient and flexible implementation of advanced signal processing algorithms along with decreasing implementation effort and costs. Therefore, we will discuss only digital systems in the present and in all of the following sections.
