- Equation for stopband transmission zeros of such lowpass filter is derived from a new equivalent circuit model. 本文基于新的等效电路模型,推导出了此类低通滤波器的阻带传输零点位置。
- The locations of transmission zeros may be simply adjusted by varying the cross-coupling capacitance or inductance. 而传输零点的位置,可简单地藉由改变产生交互耦合的电容或电感的大小去调整。
- By adjusting these transmission zeros to distribute around the spurious passbands, the stopband rejection may effectively be improved. 随著调整这些传输零点在数个不希望的谐波通带上,而达到有效压制倍频效应而延伸截止帯的目的。
- The locations of transmission zeros can be adjusted by varying the values of cross-coupled capacitances or inductances so as to improve the filter selectivity. 并且传输零点之频率可藉由变化交插耦合之电容或电感值来调整,以便改善滤波器之选择度。
- Secondly, the feed structure of filter has been investigated.A skew-symmetric feed structure, which can create two extra transmission zeros, has been proposed. 在本论文中亦针对滤波器的馈入位置进行探讨,一种可以增加两个额外传输零点响应的对称馈入架构已被发展出来。
- The mercury dived to ten below zero. 温度突然下降到零下10度。
- Now, men, zero in your guns at that ship. 喂,伙计们,把炮口对准那艘船。
- It was five below zero last night. 昨夜温度是零下五度。
- In addition to have equal-ripple response in the passband, N-degree Chebyshev functions can have at most N-2 prescribed transmission zeros to improve the selectivity or group delay. N阶柴比雪夫多项式除了在通带内是等连波响应外,可以透过预先置入最多N-2个传输零点的方式,增加通带两侧的选择度或是通带内的相位线性度。
- For the selectivity improvement, several compact microstrip coupled-line BPFs with capacitive or inductive cross-couplings to create multiple transmission zeros are proposed in Chapter 4. 在改善选择度方面,第四章提出数个微小型微带线耦合带通滤波器,并且运用电容性或电感性之交叉耦合来产生多数个传输零点。
