Lecture 7 ELE 301: Signals and Systems
Fourier Transforms. Given a continuous time signal x(t) define its Fourier transform as the function of a real f : X(f ) = ? ?. ?? x(t)e?j2?ft dt.
Lecture 8: Fourier transforms
The way to describe these frequencies is with Fourier transforms. As mentioned before the spectrum plotted for an audio signal is usually ?. ?f˜(?).
