1. This reduces gain but widens the amplifier's passband.

2. Orthonormal expansions at baseband and passband.

3. Due to the frequency pulling of FLL, the passband of the filter in PLL can be made very narrow to suppress the noise, and the PLL can lock carrier's phase with high accuracy.

4. In view of parasitic passband in the filtering networks composed of distributed elements, a novel circuit of microstrip bandpass filters is presented in this paper.

5. Passband and circuit sensitivities of the characteristics of the amplifiers are defined. They can be used as a synthetic criterion for selecting a low sensitive circuit.

6. The amplitude value of amplitude-frequency curve in frequency passband is related to damping coefficient.

7. The center frequency of the passband shifts to a higher frequency when the bias magnetic field in creases. That is good magnetotunability.

8. Sharp passband: Crystal filter and shaped audio reject QRM and QRN.

9. Requirements of passband ripple, stopband attenuation, and achieve a minimum order.

10. Using Remez exchange algorithm, equiripple passband and stopband characteristic of linear phase log filter can be directly obtained.

11. Its prominent advantages are broad tuning range, narrow passband, low power consumption, high speed continual electric-tuning, and simultaneous multiple-channel filtering etc.

12. With electrode thickness increases, passband ripple becomes smaller, center frequency moves toward lower frequency.

13. Periodic structures generally exhibit passband and stopband characteristics in various bands of wave number determined by the nature of the structure.

14. First, it uses a new kind of coupling method in the SIR filter and second, it combines the DGS structure with the newly designed filter to provide more suppression in the spurious passband.

15. Especially, regularity as one of the constraints assure the flatness in passband and the high attenuation in stopband, even the value of stopband response is very close to zero.

16. Experimental results show that the method of coupling negative resistance to resonators can improve passband performance significantly.

17. Additionally, due to the linear phase constraint, the constraint on the passband flatness becomes simpler and the design algorithm is significantly simplified.

18. Another critical factor in a magnetotelluric survey is the selection of the energy passband .

19. This paper proposes a root-finding algorithm for minimum-phase FIR digital filters which have one complex conjugate extra zero in passband.

20. The Contour filtering system provides a gentle perturbation of the IF filter passband.

21. Two parameters are used to specify the characteristics of a BPF: passband centre frequency and resonance bandwidth.

22. In the video circuit of traffic monitor, the image outline dims and the visibility declines because of the limitation of the passband, thus twice differential video compensation is needed.

23. In this paper, a novel design method of a passband edge frequency continuous adjustable FIR filter is presented.

24. In order to achieve flatter tops and sharper rolloff in the passband, the multiple-ring higher order structure is employed.

24. Sentencedict.com try its best to gather and create good sentences.

25. The filter has a pair of transmission zeros around the passband, excellent frequency response and frequency selectivity.

26. The modification of the notch filter made the extra phase-shifting introduced to the control system passband reduced and so the control performance was improved.

27. This filter has two transmission zeros on the both sides of the passband. The volume of this filter is about 1/3 or 1/2 of conventional filter.

28. According to "virtual short" and "virtual-off" feature, available to the circuit passband voltage gain and pass-band cut-off frequency.
