Computes the real Fast Fourier Transform (FFT) of the input sequence X.

![]() |
X is a real vector. |
![]() |
FFT real represents the real part of the FFT. |
![]() |
FFT imag represents the imaginary part of the FFT. |
The input sequence is real-valued.
This VI executes fast radix-2 FFT routines if the size of the input sequence is a valid power of 2.
size = 2m
where m = 1, 2,…, 10.
If the size of the input sequence is not a power of 2, this VI uses zero-filling of real data to the next power of 2.
The output sequence Y = Real FFT[X] is complex and is returned in two separate arrays—real and imaginary.
Y = YRe + jYIm
