Lecture 8: Fourier transforms - Scholars at Harvard

For a general real function the Fourier transform will have both real and imaginary parts We can write f˜(k)=f˜c(k)+if˜ s(k) (18) where f˜ s(k) is the Fourier sine transform and f˜c(k) the Fourier cosine transform One hardly ever uses Fourier sine and cosine transforms We practically always talk about the complex Fourier transform

Lecture 7 Introduction to Fourier Transforms

Fourier Transforms Given a continuous time signal x(t) de ne its Fourier transform as the function of a real f : 1 X(f ) = x(t)e j2 ft dt This is similar to the expression for the Fourier series coe cients Note: Usually X(f ) is written as X(i2 f ) or X(i!)
