Find the Fourier transformation of f(x)={x,if 0<x<a0,otherwise Fourier Transforms: In this problem we will perform the Fourier transform of the given function. Suppose that f(x) be any function defined over the interval −∞<x<∞. Then the Fourier transform of this...
Find the Fourier transform of the signal x(t)=e−tu(t), where u(t) is the unit step function. Fourier transform: Fourier transform is a method, or we can say technique in which we transform a function of time say x(t) to a function of frequency. ...
