The program is designed to help the student "get a feel" for the relationship between pole-zero placement and frequency response of digital filters and systems. Using the mouse, the user places poles and zeros around the unit circle. The resulting frequency response is displayed in absolute scale and in dB scale. The phase response is shown.
