Show how they can both be delta functions Verify that the FT of a Gaussian is a Gaussian, t2 1 202 2/o2 /2πο2 -x212 s its and so with a2=1, except for the constant 1/V2TT , e own Fourier transform. Show that they can both be delta functions (but not at the same time!). Sketch the transform cases for large and small variance. Note there are several...

1. Find the Fourier transforms of the following functions: (1) f(x) = rect * (x) * r * e * c * t * (x - 1) (2) g(x) = 2sin c * (2x) * sin(x) (3) p(x) = rect(x - 2)/2x (4) u(x) = 3sin c * (3x) - sin c * (x) (5) v(x) = sinc(x) * sinc (x) * sinc (x) 2. Find and sketch the functions and the corresponding Fourier transforms: (1) f(x) = 1/5 *...
Question: Required formulae from Question 4: Other formulae: 8. (a) If f(t) /2 show thattf. Use formulae from Question 4 to show thatpwF (the same equation in the transformed variables). It follows that F(w) - Ae-/2; evaluate the arbitrary constant A by putting w 0. Deduce that F(w) f(w) (i.e., this function is equal to its Fourier transform) (b)" Using Question 4(i), show that Fe-t2/202)-ơe_ơ2w2/2. There is a general theorem that the more widely spread out a function is, the...
Hi, I am doing some revision on Fourier Transform on my own and I got stuck on this question for five days now. Wonder if you can help me. Engineering Mathematics 4E, Anthony Croft Ex, 24.8 Q1 I want to understand how to set the lower and upper bound in each "range" by applying the floating "t" value. And how does sliding the triangle or the square block affect the convolution process. Does fourier transform gives us greater flexibility than...
