Witryna12 kwi 2024 · The wide application of power electronic devices brings an increasing amount of undesired harmonic and interharmonic tones, and accurate harmonic phasor estimation under a complex signal input is an important task for smart grid applications. In this paper, an optimization of least-square dynamic harmonic phasor estimators, … Witryna30 mar 2024 · Since the unit step signal is not absolutely integrable, we cannot find the Fourier transform using the standard formula. Hence, we will derive the Fourier transform of the unit step signal starting from the Fourier transform of the signum function. The signum function can be defined as follows:
WitrynaIn this article we give a variant of the Hermite–Hadamard integral inequality for twice differentiable functions. It represents an improvement of this inequality in the case of convex/concave functions. Sharp two-sided inequalities for Simpson’s rule are also proven along with several extensions.
