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.

Abstract translation: 计算设备使用递归离散傅里叶变换（RDFT）引擎来减少频率变换模块所需的时间，保存中间产品所需的存储器和/或用于测试的计算资源。 在一个实施例中，窗口功能与递归DFT功能同时整合和处理。 频率仓功率模块被配置为确定在各种递归水平下具有最大信号功率的频率组集合内的频率仓。
