Power and RMS Values of Fourier Series
1 . Average power Let us consider the transmission of energy from a source to a load, through a given surface as in Fig. 1. In the network of Fig. 1, the voltage waveform v(t) (not necessarily sinusoidal) is given by the source, and the current waveform is determined by the response of the load. In the more general case in which the source output impedance is significant, then v(t) and i(t) bot...
متن کاملMethods for the Anisotropic Wavelet Packet Transform
Anisotropic wavelet packets present a flexible transform with interesting properties and applications. While certain aspects of this transform have been investigated in conjunction with applications, this paper aims at providing a basic theoretical framework for working with anisotropic wavelet packets. Random decompositions are developed which have distributions with different average decompos...
متن کاملWavelet packet transform-based compression for teleoperation
This paper introduces a codec scheme for compressing the control and feedback signals in networked control and teleoperation systems. The method makes use of Wavelet Packet Transform (WPT) and Inverse Wavelet Packet Transform (IWPT) for coding and decoding operations, respectively. Data compression is carried out in low-pass filter output by reducing the sampling rate, and in high-pass filter o...
متن کاملRMS and power measurement using the dual-tree complex wavelet transform
Measurement of signal’s effective values and calculation of active-reactive-apparent-distortion powers using these measured effective values are one of the most important tasks in the energy systems. Calculations of the effective values and powers by using the classical methods are based on the Fourier transformations. On the other hand, due to the Fourier transformation having some disadvantag...
متن کاملcomparison of different methods of wavelet and wavelet packet transform in processing ground motion records
future design procedures for civil structures, especially those to be protected from extreme and blast relatedloads, will need to account for temporal evolution of their frequency content. there are, however, several instanceswhere acceleration time histories are required as seismic input. for example, to determine the ultimate resistance andto identify modes of structures’ failure, a nonlinear...
