psd ( power spectral density )造句

• To study the periodical electromagnetic pulses with random timing jitter radiated by electromagnetic pulse transmitters , the psd ( power spectral density ) of periodical electromagnetic pulses with random timing jitter was obtained based on the analysis of the - function of the psd of timing jitter
  摘要针对工程实践中电磁脉冲发射机辐射的随机时间抖动周期性电磁脉冲信号，在分析随机时间抖动周期-函数功率谱密度的基础上，得出了随机时间抖动周期性电磁脉冲串的功率谱密度。
