envelope detection meaning in Chinese

包络检波

A method for high sensitivity envelope detection of uwb pulse signals
一种高灵敏度的超宽带脉冲信号包络检测方法
Average envelope detection
平均包络检波
In this paper a design of a digital b scan system is proposed . the digital quadrature envelope detection is used to detect the envelope of ultrasound , and a simulated result is given
本文致力于模拟b超的数字化工作，将正交数字包络检波方法用于超声回波信号的提取，并给出了仿真结果。
Then , digital quadrature envelope detection is used to detect the envelope of ultrasound as it is most used in the corresponding signal process . at last , we transform the signal to the range which can be displayed by the logarithm transform
有效补偿了超声传播过程中的吸收衰减;并将正交包络检波技术用于超声信号的幅度检测;最后通过对数压缩得到了显示需要的灰阶信号。
