The Fast Fourier Transform is at the heart of real-time spectrum analysis. In the RTSA, FFT algorithms are employed to transform time-domain signals into their frequency-domain spectral components.

Approval of NERC's "Find, Fix & Track" procedure affirms NERC's efforts to streamline the resolution of low-risk Reliability Standard violations. In a move intended to improve the efficiency of the ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

The Federal Energy Regulatory Commission (FERC) recently issued an order conditionally accepting a proposal by the North American Electric Reliability Corporation (NERC) to include “Find, Fix, Track ...

Optical transmission systems with terabit per second (Tbit s −1) single-channel line rates no longer seem to be too far-fetched. New services such as cloud computing, three-dimensional high-definition ...

Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...
