RF/Microwave Filters | Lecture 02 - Basic Definitions and Responses

Journey into the world of filter synthesis with Purdue University’s Dr. Dimitri Peroulis, as he presents the fundamental principles. This video lecture explores the use of scattering parameters to define the filter's power transmission and input reflection responses. For a lossless network, specifying one of these responses usually implies the other. While the focus of the course is on synthesizing filters based on magnitude response alone, Dr. Peroulis also emphasizes the importance of understanding both transmission and reflection responses to fully define a filter. He also discusses group delay, and the trade-off between group delay and selectivity in determining a filter's performance.
