, Fast Fourier Transform FFT
- A fast Fourier transform (FFT) is an efficient algorithm to compute
the discrete Fourier transform (DFT) and inverse of DFT.
- There are many FFT algorithms which involves a wide range of
mathematics,. A Discrete Fourier transform decomposes a
sequence of values into components of different frequencies.
- This operation is very useful in many fields but computing it
directly from the definition is often too slow to be practical .
, Cont ..
• FFT are special algorithms for speedier implementation of DFT.
• FFT requires a smaller number of arithmetic operations such as
multiplications and additions than DFT.
• FFT also requires lesser computational time than DFT .
