A frequency-response curve of a loudspeaker is defined as the variation in sound pressure or acoustic power as a function of frequency, with some quantity such as voltage or electrical power held constant. From: Acoustics: Sound Fields and Transducers, 2012 ...

The presented approach is frequency-domain based and can therefore directly be used to tune, among others, proportional integral derivative controllers, low/high-pass filters, and notch filters, using a Frequency Response Function of the plant. The approach taken in this paper is to extract the ...
Earlier results available in the literature show that, when the dissipation is large enough and a suitable function involving the forcing has a simple zero, response solutions can be proved to exist and to be attractive provided some Diophantine condition is assumed on the frequency vector. In ...
The methodological emphasis is on extending the volume swing frequency response (FR) method to problems with strong heat transfer limitation. The heat and mass transfer parameters are mapped to the sample temperature and loading state, in order to be able to reproduce the strongly non-linear ...
When friction between two surfaces supplies the damping mechanism, the response to a harmonic input is no longer harmonic because of the nonlinearity in the system. There may still be a periodic, but anharmonic, response. Such problems cannot be solved by the frequency-domain methods, in which...
If headphone's frequency response is 4 dB below the target at 20 Hz equalization function will have +4 dB boost at 20 Hz. In reality simply inverting the error is not sufficient since measurements and equalization have several problems that need to be addressed, see Technical Challenges for ...
IoT devices that need precise, continuous location data should use multiple GNSS constellations and frequencies simultaneously to improve accuracy and resilience. Multifrequency, multiconstellation GNSS is associated with increased power consumption. However, low-power GNSS solutions and techniques like adaptiv...
The dynamic response of the complex systems can be examined by two approaches: time domain solution and the frequency domain solution. Up to now, all solutions have been in time domain and the equations are solved by integrating with time. In frequency domain technique, the amplitude coefficients...
Based on bifurcation theory, nonlinear frequency response analysis is a recent development in the field of flight dynamics studies. Here, we consider how t
