\brief Fast Fourier Transform Object Data Structure
|
||
|
||
The structure stores pointers to twiddle factors and arrays of intermediate
|
||
data of the fast Fourier transform algorithm.
|
||
|
||
The libdspl-2.0 library uses an FFT algorithm for composite size.
|
||
|
||
\param n
|
||
The size of the FFT vector for which memory is allocated
|
||
in the structure arrays. \n
|
||
The parameter `n` must be equal to an integer power of two (radix 2). \n \n
|
||
|
||
\param w
|
||
Pointer to the vector of twiddle factors. \n
|
||
The size of the vector is `[n x 1]`. \n
|
||
The memory must be allocated and an array of twiddle factors
|
||
must be filled with the \ref fft_create function. \n\n
|
||
|
||
\param t0
|
||
Pointer to the vector of intermediate results of the FFT algorithm. \n
|
||
The size of the vector is `[n x 1]`. \n
|
||
Memory must be allocated by \ref fft_create function. \n\n
|
||
|
||
\param t1
|
||
Pointer to the vector of intermediate results. \n
|
||
The size of the vector is `[n x 1]`. \n
|
||
The memory must be allocated with the \ref fft_create function. \n\n
|
||
The structure is populated with the \ref fft_create function once
|
||
before using the FFT algorithm. \n
|
||
A pointer to an object of this structure may be
|
||
reused when calling FFT functions. \n
|
||
Before exiting the program, dedicated memory for twiddle factors and arrays of
|
||
intermediate data must be cleared by the \ref fft_free function.
|
||
|
||
For example:
|
||
|
||
\code
|
||
fft_t pfft = {0}; // Structure fft_t and clear all fields
|
||
int n = 64; // FFT size
|
||
|
||
int err;
|
||
|
||
// Create and fill FFT structure for 64-points FFT
|
||
err = fft_create(&pfft, n);
|
||
|
||
// FFT calculation here
|
||
// FFT calculation here one more
|
||
// ...
|
||
|
||
// Clear fft structure
|
||
fft_free(&pfft);
|
||
\endcode
|
||
|
||
\note
|
||
It is important to note that if the object `fft_t` was created for the FFT size
|
||
equal to` n`, it can only be used for FFT of size `n`. \n \n
|
||
It’s also worth noting that the FFT functions independently control the size,
|
||
and independently allocate the memory of the FFT object, if necessary.
|
||
So if you call any function using the `fft_t` structure with filled
|
||
data for the FFT length `k` for calculating the FFT of length`n`,
|
||
then the structure arrays will be automatically recreated for the length `n`.

\brief
|
||
The macro returns the square of the modulus of a complex number `x`.
|
||
|
||
Square of the modulus of a complex number \f$ x = a + j b \f$ equals:
|
||
|
||
\f[
|
||
|x|^2 = x x^* = a^2 + b^2.
|

\f]

Example:
|

\code{.cpp}

complex_t z;

double y;
|
||
RE(z) = 1.0;
|
||
IM(z) = -2.0;
|
||
y = ABSSQR(z);
|
||
\endcode
|
||
|
||
Variable `z = 1-2j`, here `j` - imaginary unit, but variable `y = 5`.
