which shows that $h[n]$ is a linear phase filter.
In the complex world of electrical engineering, computer science, and applied mathematics, few textbooks command as much respect—and anxiety—as Mathematical Methods and Algorithms for Signal Processing by Todd K. Moon and Wynn C. Stirling. This text is not merely a book; it is a rite of passage. It bridges the gap between abstract linear algebra, optimization theory, and the practical algorithms that power modern communication systems, image processing, and machine learning. which shows that $h[n]$ is a linear phase filter
h[n] = 0.54 - 0.46cos(πn/M)
