mot566_ifft (Motorola DSP Developer's Kit)

Compute the IFFT of the input.

MATLAB Syntax

Y=mot566_ifft(X)
Y=mot566_ifft(X,N)
Y=mot566_ifft(X,N,DIM)

Description

mot566_ifft(X) is the inverse discrete Fourier transform of X.

mot566_ifft(X,N) is the N-point inverse transform.

mot566_ifft(X,N,DIM) is the inverse discrete Fourier transform of X across the dimension DIM.

Characteristics

In the workspace, if the input is:

 X = [-0.0023 - 0.0101i  -0.0446 - 0.0229i  -0.0634 - 0.0223i
      -0.0701 - 0.0234i  -0.1196 - 0.0103i  -0.0244 - 0.0014i]

then execute the function:

 mot566_ifft(X,2,2)
 ans=-0.0234 - 0.0165i   0.0211 + 0.0064i
     -0.0948 - 0.0168i   0.0248 - 0.0066i

Argument
X
Vector (or matrix) with elements normalized in the range [-1,1] (for complex elements, both real and imaginary parts should comply with this limit).

N
Scalar defining the number of inverse transform point.

DIM
Scalar defining the dimension when the inverse transform is performed across a matrix.
