Design and Comparison Between IIR Butterworth and Chebyshev Digital Filters using MATLAB

In the complex world of digital signal processing, successfully manipulating digital signals relies on using digital filters with expertise. This well-prepared research paper takes a thorough approach to explore and examine a topic in great detail. In simpler terms, it carefully investigates and analyzes a subject, and insightful comparison of Infinite Impulse Response filters. The epicenter of this scholarly exploration rests upon three pivotal filter design methods: the venerable Butterworth, the versatile Chebyshev, and the sophisticated Elliptical filters. Paramount parameters—the sampling frequency, stopband frequency, passband frequency, stopband ripple and passband ripple —are subjected to rigorous scrutiny within the intricate tapestry of IIR filter engineering, revealing profound insights.
