Examples
- The key purpose of the subject is in order to validate the feasibility of dds / pll in the spreading band
其主要目的是验证dds / pll在频带扩展方面的可行性。 - Recently , there is a great interest in researching 4kb / s toll - quality speech coders and the technology of speech bandwidth extension
拥有长途话音质量的4kb / s语音编码及其频带扩展技术是当前研究的热点。 - Firstly a microstrip - fed microstrip patch antenna has been emulated and validated . on the base of this , the multi - band property of sierpinski equilateral triangle and squareness microstrip fractal patch antennas are carefully studied , and the effect of antenna ' s property by the permittivity , the size of patch , the order of the fractal and the decrease of fractal patches is depicted ; secondly on the base of analysis and comparison of performance of microstrip - fed semicircle and rectangle double - band microstrip patch antennas , warranty of dimension curtailment is offered ; finally expansion of band of those antennas above is discussed
在此基础上，着重分析了微带线耦合馈电的sierpinski等边三角形微带分形贴片天线以及sierpinski方形微带分形贴片天线的多频特性，给出了介质参数、贴片尺寸、分形的阶数以及减少分形贴片数对微带线耦合馈电的sierpinki等边三角和sierpinski方形微带分形贴片天线特性的影响；其次基于微带线耦合馈电的半圆双频微带贴片天线和矩形双频微带贴片天线的性能分析和比较，提供了尺寸缩减的依据；最后对以上天线的频带扩展进行了探论。
