FIR design: optimal minimax

This lecture covers the optimal minimax design of Finite Impulse Response (FIR) filters, focusing on the algorithm developed by Parks and McClellan in the 70s. It explains the linear phase Type I design, the minimax lowpass filter, and provides examples of magnitude response in decibels. The lecture also explores the application of FIR methods beyond lowpass filters, including bandpass and highpass designs.
