1. Based on analysis of the periodic concomitant response of model T Low-Pass Filter(LPF), a microstrip filter of Electromagnetic Band Gap(EBG) structure was designed that satisfied Bragg equation.
2. When designing the LPF based on ideal Op Amps, the coupling effects of nonideal Op Amps are omitted, resulting in dissatisfactory performance of LPF.
3. In this paper, impedance matching between LPF and surveying instrument is discussed and the design method is presented.
4. SDH, LDH, LPF were detected by the immunohistochemical method, and the histological changes were synchronously observed by electronic microscope.
5. A kind of speed sensor-less DTC method with a programmable low pass filter(LPF) to estimate stator flux was presented.
6. First, the basic principle of the phase-locked loop circuit is introduced in this paper. Second, the discussion and improvement of the design of the low passed filter (LPF) is presented.
7. LPF operates when a logout request comes from a client.
8. With a newly developed Degradated Ply Stiffness Theory and "Uniform Degradated Stiffness Coefficient" from experiments, the last ply failure(LPF)is predicted.
9. The activities of SOD, MDA, and LPF in brain tissues were tested using nitrite method, thiobarbituric acid colouration method(Sentence dictionary), and fluorescence measurement.
10. You can see that LPF takes two parameters in its constructor: the logout success URL (/logoutSuccess.jsp) and a list of handlers.
11. The former method is simpler in algorithm and implement, and the latter has lower requirement of low pass filter(LPF).
12. The improved delay unit in VCDL efficiently lowers the output jitter and a low-pass filter (LPF) is designed to avoid the charge-sharing error.
13. The proposed CPPLL is made up of a no dead zone phase frequency detector(PFD), a loop filter(LPF), a charge pump(CP), a voltage-controlled oscillator(VCO) and dividers.
14. Nowadays, research about SAPF is mainly focused on the detection of the v o ltage distortion and little on LPF, which influence the systemic feature of SAPF .
15. Therefore, based on detail research, a frequency-varied design and optimization method for LPF is presented in this paper.
16. In this method, the PD negative feedback is proposed, which can compensate for the inherent delay of LPF and quicken the dynamic response speed evidently.
17. These are also simulated on computer and the results show that the LPF method is more suitable for the quadrature sampling of wideband IF signal.
18. The power supply of the source clock and the LPF can be shut off by system controller at idle time.
19. Fundamentals of IF(Intermediate Frequency) bandpass signal sampling and quadrature detection are discussed, especially the coherent mixing LPF method and Hilbert transform frequency-shift method.
20. Under special conditions a BPF may also be used as an LPF or as an HPF.
