Basics of filters in radar signal processing

This video describes analog and digital filters used in signal processing.

It explains the basics of simple analog filters and shows the filter characteristics of some digital filters, such as the Chebyshev filter and the elliptical filter.

This video is part of a training course from www.radartutorial.eu.
