Fourier transform from Laplace transform-The Fourier transform of finite support signals, which are absolutely integrable or finite energy, can be obtained from their Laplace transform rather than doing the integral. Consider the following signals 5.30 x3(t) - r(t + 1) - 2r(t) + r(t - 1) (a) Plot each of the above signals. (b) Find the Fourier transforms (X,(S2)) for1, 2, and 3 using the Laplace transform (c) Use MATLAB's symbolic integration function int to compute the Fourier transform of...

Simplify ths expression as much as po e simplest expression does not involve any complex numbers.) Draw a rough plot of o) as a function of w. Identify the peak value of X(w). Identify the location of the X( first null on either side of the vertical axis.
How to graph fourier transform My question isn't on how they got the transform, my question is how the graph was calculated, I don't know what sinc means Note: 1) In the following problem set a notation Pa(t) is used to denote an even pulse (i.e. rectangular) shape function with the duration of a. This means that for example the function x(t) in question number one is 2P2(t-1). It is clear that using the properties of Fourier transform is greatly...
Find the signal x(t) whose Fourier Transform X(jω) is as follows: 0 otherwise Note that the magnitude signs around w in the definition of X(jo) mean that it is symmetric around the origin (that is, it is even). Also note that you can solve this problem using direct integration, tables, or a combination.
