A Signal Theoretic Approach for Envelope Analysis of Real-Valued Signals
IEEE Access, 2017 Analytic envelope is the most prevalent definition of envelopes of real-valued signals. However, analytic signals are not adopted by some envelope detectors in application.

Negative frequencies in pulse propagation equations and the double analytic signal
New Journal of Physics, 2023 In recent years, the topic of negative frequencies has resurfaced in optics motivated by the optical analogue of Hawking radiation. We discuss the physical meaning of negative frequencies and the conditions under which they are relevant.

Efficient Estimation of the Helicopter Blade Parameter by Independent Component Analysis
IEEE Access, 2020 We propose an efficient method to estimate various parameters of a helicopter blade including the number Bnum and the length by separating the blade signal using independent component analysis (ICA) and an analytic solution obtained by monostatic ...

An analytical solution for the SSFP signal in MRI [PDF]
Magnetic Resonance in Medicine, 2003 AbstractAmong previous analyses of the steady‐state free‐precession (SSFP) signal in rapid MRI, one treatment resulted in equations that require the evaluation of infinite binomial series. Here, an analytical solution is derived by a transformation into the power series expansion of the derivative of the inverse sine function, which is essentially a ...

New method for edges detection of magnetic sources using logistic function
Геофизический журнал, 2018 The tilt angle of the analytic signal amplitude (TA) is defined as the arctangent of the ratio of the first vertical derivative to the total horizontal derivative of the analytic signal amplitude. It is commonly used as a useful tool to estimate edges of

Interpretation of magnetic anomalies using the horizontal gradient analytic signal
Annals of Geophysics, 2001 In recent years the analytic signal method has been of great utility in the interpretation of potential field data. The amplitude of the 3D analytic signal of magnetic data yields information on the location of the edges of the sources in both the ...
