Development of Swept Frequency Method for Measuring Frequency Response of Photodetectors Based on Harmonic Analysis

, 2009
We develop a swept frequency method for measuring the frequency response of photodetectors; (PDs) based on harmonic analysis. In this technique, a lightwave from a laser source is modulated by a radio-frequency (RF) signal via a Mach-Zehnder LiNbO3 ...

Bifurcations of backbone curves for systems of coupled nonlinear two mass oscillator [PDF]

, 2014
This paper considers the dynamic response of coupled, forced and lightly damped nonlinear oscillators with two degree-of-freedom. For these systems, backbone curves define the resonant peaks in the frequency-displacement plane and give valuable ...

Method for filtering proportional valve-frequency-response test data containing impulsive noise

Advances in Mechanical Engineering, 2019
Impulsive noise, generated by inverters and other equipment used in the field, tends to easily enter test channels in scenarios where continuous frequency conversion signals are employed to test the frequency response of electrohydraulic proportional ...

Performance analysis of global local mean square error criterion of stochastic linearization for nonlinear oscillator

Vietnam Journal of Mechanics, 2019
The paper presents a performance analysis of global-local mean square error criterion of stochastic linearization for some nonlinear oscillators. This criterion of stochastic linearization for nonlinear oscillators bases on dual conception to the local ...

ANALYSIS OF RUNOFF BY FREQUENCY RESPONSE METHOD

Doboku Gakkai Ronbunshu, 1988
The existence of dead time and delay time is recognized in one-component input-output system response. These two effects should not be regarded as identical. Various reports have been given on delay time over a long time as an important concept to explain the mechanism of rainfall-runoff process, that is, concentration time of flood.
