According to the results of theoretical analysisand experimental research, this paper gives approximate formulae to predict the frequency bandwidth and the steady-state error of the regulators.
Influence of Duffing system parameter on chaotic signal frequency bandwidth;
When the porosity and pore diameter reduced, the sound absorption curve moved to the low frequency zone and the frequency bandwidth increased at the same time.
This method broadens the silence frequency bandwidth of muffler and improves its silence fuction.
Contrarily, if the frequency bandwidth of signal is finite, the time length of signal will be infinite when sampling in frequency domain, the time folding phenomenon will certainly happen.
By utilizing two field regions with stronger EM field intensity, the pentagon antenna has not only higher EM intensity, but also over twenty times frequency bandwidth.
occupied frequency bandwidth
Analyzed is the dependence of the defocusing quantity on the hologram size and the spatial frequency bandwidth of the object.
In addition decreasing the beam radius can also enhance the frequency bandwidth of the guide wave;
