Linear Phase Filters: Theory and Design

This lecture covers the theory and design of linear phase filters, discussing concepts such as group propagation time, polar form of the frequency response, differential formula for group delay, and the necessary conditions for achieving linear phase filters. It also explores the synthesis of digital filters, Chebyshev criterion, and the placement of poles and zeros. The lecture emphasizes the importance of achieving linear phase clamps and symmetrical linear phase filters for optimal filter performance.
