EMB Inverse Real FFT (DSP Module)
Computes the inverse real Fast Fourier Transform (FFT) of a real and imaginary input sequence.
 |
FFT real represents the real part of the FFT. |
|
FFT imag represents the imaginary part of the FFT. |
 |
X is the inverse real FFT. |
EMB Inverse Real FFT Details
The input sequence is complex-valued and operates on two separate real and imaginary arrays.
This VI executes inverse 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 and imaginary data to the next power of 2.
