[PDF] Complex Floating Point Fast Fourier Transform - NXP
The fast Fourier transform (FFT) reduces the number of calculations of the DFT by dividing the initial function into repeated subfunctions and continues this

The FFT takes complex numbers as it input4 If the input is a not a complex signal, the imaginary parts of the input are zero and the output curves will be symmetrical about the N/2 point This implies a lot of wasted computation This can be skipped, giving the real FFT

When you multiply two complex numbers, their magnitudes multiply z 1 Remember: The FFT is just a faster algorithm for computing the DFT — it does not

Figure 2 1: Illustration of the relationship between the real and imaginary parts of the complex number x and its magnitude and phase 2 1 1 Useful rules and
[PDF] The Complex Fourier Transform
Although complex numbers are fundamentally disconnected from our reality, can be used to make the FFT algorithm calculate the frequency spectra of two
[PDF] The Fast Fourier Transform
Since the FFT is an algorithm for calculating the complex DFT, it is important to FFT, but skirts a key issue: the use of complex numbers If you have a
