Theorem 2.1: Let f: D-->R with x0 an accumulation point of D. Then f has a limit at x0 iff for each sequence {xn}^inf_n=1 convening to x0 with xn in D and xn≠x0 for all n, the sequence {f(x)} converges Exercise 2.24.8 Assume that f,g : D → R, that 20 s an accumulation point of D, and that α, β R. Assume that limr. J-F, and limrog-G. Define af +ßg to be the function D R given by (af...
Using parsevals theorem and FT to find y(t) and its power (b) (4 pts) Fourier Series The input signal r(t) and impulse response h(t) of an LTI system are as follows: z(t) = sin(2t)cos(t)-e131 + 2 and h(t) = sin(21) Use the Fourier Series method to find the output y(t) (c) (4 pts) Parseval's Identity and Theorem. Consider the system in the previous problem. Use Parseval's Identity to compute the power P of the output y(t). Use Parseval's Theorem to...
1) Suppose f (a, b) R is continuous. The Carathéodory Theorem says that f(x) is differentiable at -cE (a, b) if 3 (a, b)-R which is continuous, and so that, (a) Show, for any constant a and continuous function (x), that af(x) is continuous at z-c by finding a Carathéodory function Paf(x). (b) Show, for any constants a, B, that if g : (a, b) -R is differentiable at c, with Carathéodory function pg(z), then the linear combination of functions,...
