Abstract
A method and system (10) are provided for monitoring an operating state of an engine (12). Data are measured (84) from the engine (12). The data are indicative of the operating state of the engine (12). The data are processed (86, 90, 92) according to a discrete Fourier transform. The operating state of the engine is monitored by processing (96-114) the discrete Fourier transform.
