Maximum Frequency Deviation Calculation in Small Isolated Power Systems
IEEE Transactions on Power Systems, 2009 Artículos en revistasLarge frequency deviations due to a number of disturbances are frequent in small isolated power systems. The maximum frequency deviation in the system is limited to prevent other generator tripping.

Standard deviation of instantaneous frequency
International Conference on Acoustics, Speech, and Signal Processing, 2003Explicit expressions are derived for the standard deviation of instantaneous frequency (local bandwidth) at a particular time using the short-time Fourier transform and the general class of bilinear distributions. Examples are given. Application to the characterization and description of a multicomponent signal is discussed.

Language Deviations in Aphasia: A Frequency Analysis
Brain and Language, 1993Thirty right-handed left hemisphere-damaged patients were taken and divided into five groups (transcortical motor, Broca, conduction, Wernicke, and anomic aphasia). Language deviations were scored and analyzed for the Picture Description (Plate No. 1, The Cookie Theft), Repetition (Words, High and Low Probability Sentences), and Naming (Responsive ...

A Method for Frequency Deviation Measurement
2006 IEEE International Power and Energy Conference, 2006A simple technique is developed for measurement of power frequency deviation. It is based on multiplication of two signals having different frequencies and then filtering out the higher order frequency component. The lower order frequency component is converted into a square wave and modulated with a high frequency pulse train.

An electronic frequency deviation transducer
International Journal of Electronics, 1982A solid state frequency deviation transducer suitable for continuous recording of power system frequencies has been developed. The device is based on a digital— analogue technique and makes use of linear and digital integrated circuits for its implementation.

Digital converter of frequency deviation based on three frequency generator
East-West Design & Test Symposium (EWDTS 2013), 2013In the work the synthesis of digital converters of frequency deviation is considered. The synthesis is based on self-oscillation system with combinative interaction of the three frequencies in the mode of increased sensitivity. This mode is achieved by the inclusion of two cascaded amplifiers with a typical and an inverted phase-frequency ...
