Unformatted text preview: Skip the discussion surrounding equation 2.3 and concentrate on page 78. Equation 2.6 is the key. It is a restatement of superposition. We will introduce an array method, not in the text, for handling finite sequence problems. Understand the general graphical approach for setting up the convolution sums and the limits on the sums given in the text examples 2.1, 2.2, 2.3 and 2.4. Study videos 3.1, 3.2, and 3.4. Some of these videos as well as the text examples require summation formulas developed in video 3.3 (See text, problem 1.54, p73). Video 3.4 is a detailed solution for text example 2.4. Start with the problem statement in the text, and try to solve the problem by yourself. Then check your solution and procedure with the one given in the text. If you are still having difficulty, then consult video 3.4....
