RESPITE: The CASA Toolkit Page: Documentation: Block Library Index:FFT


Employs the Fast Fourier Transform algorithm to compute the modulus of the Fourier Transform of each frame of input data.

Note, if necessary inputs frames are zero padded so that their width is an integer power of 2. The width of the output frame will be half the width of the padded input frame.

Inputs Meaning Sample 1-D frame $\ge$2-D frame
in1 1-D frame input data No Yes No

Outputs Meaning
out1 1-D frame data after |FFT|

Parameters Type Default Meaning
No parameters
