相移网络 phase-shift network
phase-shifting network
- 驻极体传声器目前主要是民用,单指向性驻极体传声器设计与生产的关键在于内部相移网络的控制。
The key technique in design and manufacture of unidirectional ECM is how to control the internal phase-shift network. - 在DFT处理器中除WFTA运算器外,还有一个辅助的相移网络和一个供同时处理两个60路超群信号的分离(或组合)单元。
In addition to the WFTA processor, an auxiliary phase shifting network and a signal separator (or combiner) for two 60-channel supergroups are included in the DFT processor. - 然后利用遗传算法分别对30和60十倍频宽带相对相移网络的零极点参数值进行了优化,得到了较好的相位频率特性结果;
The Genetic Algorithm(GA) is used to optimize the pole-zero location in all-pass networks of 30 and 60 relative phase-shift, and good phase-frequency characteristics are obtained.
