Introduction to Digital Filter Design

http://adampanagos.org This playlist of videos provides a short introduction to designing digital filters. In this first video, we review some basic filtering concepts. The Frequency Response of a filter describes how the amplitude and phase of an input signal change as a function of signal frequency. For an input of a single-frequency cosine, we derive the output signal showing how the input amplitude changes by a factor of |H(omega)| and the phase changes by an amount of arg(H(omega)). We call|H(omega)| the Amplitude Response of the system and arg(H(omega)) the Phase Response of the system. In subsequent videos, we’ll learn how to design digital filters that have desired amplitude response and phase response characteristics. The next video in this playlist is: Computing the System Frequency Response from Difference Equation -    • Computing the System Frequency Response fr...   Join the channel for membership perks:    / @adampanagos   Course website: https://www.adampanagos.org/dt-signal...
