Unformatted text preview: +∑ L Using (t = 1:0.1:10) and MATLAB’s for loop of n = 0:15 approximate the cosine signal from the above formula and call it x1. Plot x1 with the actual cos(t) on one graph to verify your result (use for, factorial, cos and subplot commands in MATLAB). Problem 2. Is the system of gG±² = G4± − 2²³G±² timeinvariant? Is the system linear? Simulate the system in MATLAB and show plot(s) of the input(s)/output(s) that supports your answer. Prove your result with analytical work. Problem 3. Consider the following differential equation where gG0² = 2 : ´gG±² ´± + 3gG±² = 2³G±² Find the solution using the method of undetermined coefficients given that ³G±² = µ ¶·¸ ¹G±². Find the step and impulse responses analytically and verify all of your results with MATLAB using lsim , step and impulse ....
