We discuss the effect of the estimation of the amplitude variations on the noise-induced frequency shift in nonlinear oscillators. The analysis is based on a general reduction approach to a phase ...

This paper addresses the problem of estimating the instantaneous frequency (IF) and amplitude of the modes composing a non-stationary multicomponent signal in the presence of noise. A novel ...

Jun 18, 2025 07:00:00 A graph showing how many abusive words such as 'fuck,' 'shit,' and 'stupid' are contained in the Linux source code, and the frequency of 'fuck' has dropped dramatically since ...

The traditional technique is to measure and record the exciting impulse and the resulting response current using a digitizer with sufficient amplitude resolution (generally accepted as at least 9 bit, ...
