| 2. | Traditional static crosstalk identification methods identify crosstalk targets only using coupling capacitance and noise amplitude information , which lead to the pessimistic results and induce a long time to ic design convergence
摘要传统的静态串扰噪声识别算法只验证耦合电容和噪声幅值信息，没有考虑噪声宽度对电路逻辑功能的影响，所以给出的结果过于保守，导致设计收敛的时间被延长。 |
| 3. | Quartered demodulating technology is widely applied in modern if receiver because it can extract phase and amplitude information from the received signal . the quadrature demodulating component in traditional receiver was implemented with analog circuits
在现代雷达系统中，宽带雷达信号应用的越来越广泛，相应地，通过数字信号处理的方法来处理超宽带雷达信号，需要高速的数据采集系统来提取信息。 |
| 4. | The reasons focusing only on ray travel times are " noise tolerance could be enhanced and the sensitivity to the environment model mismatch may be reduced by neglecting amplitude information ; phase ambiguity is eliminated by employing the group delay of arriving wave packets ; travel times are pseudo - linear functions of sound speed profiles of the medium , and the perturbation of ray travel time is much smaller than sound pressure ' s
之所以选择声传播时间的原因是：噪声容限可以得到提高，并且传播时间的计算可以不考虑声压的信息，从而降低了对环境模型失配的敏感性；相位的起伏也可通过到达包络的群延时来消除；传播时间是介质声速分布的伪线性函数并且传播时间的起伏远小于声压的起伏。 |
| 5. | Conversion of signals from if analog into digital samples carrying phase and amplitude information has been traditionally implemented in the form of two parallel if to baseband converters operated in quadrature each followed by a / d converters which thus provide digitized in - phase ( i ) and quadrature ( q ) components
对于传统雷达信号接收机，幅相一致性较差。为克服这一问题，人们考虑在中频，甚至射频就对信号数字化，再在数字域内进行解调。同样需要高速的数据采集系统才能满足要求。 |
