Abstract
A computing device uses a recursive discrete Fourier transform (RDFT) engine to reduce time required by a frequency transform module, memory required to hold intermediate products, and/or computing resources used for the testing. In an embodiment the windowing function is integrated and processed simultaneously with the recursive DFT funcions. A frequency-bin power module is configured to determine the frequency bin within the set of frequency bins that has a greatest signal power at various levels of recursion.
