noise power spectrum meaning in Chinese

噪声功率谱

Phase noise power spectrum density
相位躁声功率频密度
So , both 1 / f noise power spectrum measurement and similarity coefficient extracted from its time series can offer economical , effective and indestructible tool to detect the latent damage induced by esd and hci for mosfets
因此，无论是1 / f噪声功率谱的测试还是由其时间序列提取得到的相似系数均可以作为经济、有效、完全非破坏性的工具，替代传统的电特性用于检测静电引起的mos器件潜在损伤以及热载流子注入损伤。
Welch , 1967 ) , the author calculated noise power spectrum of every site to see if the noise level of the array site accord with ims standard ( the noise level at 5 hz must lower than - 135db ) , and the result suggest that the noise level accord with the ims standard . to find out the principle of noise ' s variation , the root mean square of every site had been calculated and analysised , the result show that several sites had obvious daily variation which is relevant to the tv transmittion tower on the top of dajianshan
Welch ， 1967 )对台阵阵址各测点的噪声功率谱进行了计算与分析并对各测点的噪声均方根值做了计算，结果表明台阵的背景噪声达到了ims要求的标准(即在5hz处噪声功率谱要小于- 135db ) ，多数测点的噪声有明显的日变化规律，这与大尖山顶的tv发射塔有关。
