www.st.com3.2 Transforms. A transform is a function that converts data from a domain into another. The FFT (Fast Fourier Transform) is a typical example: it is an efficient algorithm used to convert a discrete time-domain signal into an equivalent frequency-domain signal based on the Discrete Fourier Transform (DFT).
Applications of the Fourier Series
sces.phys.utk.eduComparing equation (6) with the Fourier Series given in equation (1), it is clear that this is a form of the Fourier Series with non-integer frequency components. Currently, the most common and e cient method of numerically calculating the DFT is by using a class of al-gorithms called \Fast Fourier Transforms" (FFTs). The
