ECE 220 Multimedia Signal Processing October 12, 2006 Fall 2006 The following is a list of topics and concepts in the material which exam 1 will cover. This is a comprehensive listing of what we’ve done; obviously the exam cannot test everything and appearance of a concept on this sheet does not guarantee it will appear on the exam. This page outlines what you’re expected to have gotten out of the lectures, demonstrations, homeworks, and labs. The exam is cumulative Frequency Response ( Sections 6-1, 6-2, 6-4 to 6-7) Frequency response: definition and evaluation. Finding the frequency response of a DT system given either a difference equation or an impulse response. Finding cascade and parallel system responses in the frequency domain. Definition of the Discrete-time Fourier Transform (DTFT) and inverting the DTFT to get DT signals. Definition of an ideal low-pass filter.
