Explain the differences and similarities of a trigonometric Fourier series and a Fourier transform of a square wave Explain why Fourier transforms have negative frequency and the significance Please be as detailed as possible for both points. Thank you
9. Find the Fourier series coefficients and Fourier transform for each of the following signals: a) x(t)= sin(10nt+ b) x(t) = t) 1 + cos(2π cos (2rt S2n
Typed please. What is Fourier Series? How it is different from Fourier Transform? Explain with an example.
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...
1-Can we calculate the Fourier Transform for a function represented by Fourier Series? Elaborate. 2-What happens if we sample with a frequency that is less than half the maximum frequency of the sampled signal? 3-Describe in your words what is Fourier Series and its relation to periodic signals. Mention whether it is a time domain or frequency domain representation
This is a fourier series/ transform question Consider an LTI system whose response to the input x)lee3ut) is y)12e-2e4Ju) (a) Find the frequency response of this system. (b) Determine the system's impulse response (c) Find the differential equation relating the input and the output of this system.
**INVERSE FOURIER TRANSFORM**
c) Find the Fourier transform of the function et. Using this find the Fourier transform of re-.
