The Robustness of Least-Squares Frequency Switching (LSFS)
Least-squares frequency switching (LSFS) is a new method to reconstruct signal and gain function (known as bandpass or baseline) from spectral line observations using the frequency switching method. LSFS utilizes not only two but a set of three or more local oscillator (LO) frequencies. The reconstruction is based on a least squares fitting scheme. Here we present a detailed investigation on th...
متن کاملA New High Frequency Grid Impedance Estimation Technique for the Frequency Range of 2 to150 kHz
Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...
متن کاملOptical heterodyne spectroscopy with frequency- and amplitude-modulated semiconductor lasers.
Optical heterodyne spectroscopy has been performed with GaAlAs diode lasers by modulating the injection current at frequencies up to 2.6 GHz. This extremely convenient modulation scheme results in simultaneous frequency and amplitude modulation of the laser output. When the modulated laser output probes a narrow absorption line, a characteristic heterodyne beat signal occurs. We show that the o...
متن کاملA new technique for bearing fault detection in the time-frequency domain
This paper presents a new Fast Kurtogram Method in the time-frequency domain using novel types of statistical features instead of the kurtosis. For this study, the problem of four classes for Bearing Fault Detection is investigated using various statistical features. This research is conducted in four stages. At first, the stability of each feature for each fault mode is investigated. Then, res...
متن کاملFew-photon heterodyne spectroscopy.
We perform a high-resolution Fourier transform spectroscopy of optical sources in the few-photon regime based on the phenomenon of two-photon interference in a beam splitter. From the heterodyne interferogram, between test and reference sources, it is possible to obtain the spectrum of the test source relative to that of the reference. The method proves to be a useful asset for spectral charact...
