噪音整形产生的问题,就是小信号的损失——信号小于噪音整形本底噪音的就是损失的信息量。
The problem with noise shaping is that small signals get lost - any signal below the noise shaper noise floor is lost information.
根据信号、本底的时间分布以及时间、时间误差、质量、质量差等变量之间的关系,构建概率密度函数。
The probability density function (PDF) is constructed from the time distributions of signal and backgrounds and the relations among time, time uncertainty, mass, and mass difference variables.
该电路用在北京谱仪触发判选系统中,作为排除由于干扰信号造成主漂移室成片着火的本底事例。
This circuit is used in BES Trigger System to reject the background caused by interference in MDC.
设计的信号补偿电路,扣除了直照信号的本底干扰,提高了探测器的信躁比。
The signal compensation current degrades the radiation background and increase the signal-noise ratio respectively.
另外,快速傅里叶变换方法由于不受本底噪声影响,可以不必在信号处理时去掉本底噪声,因而可以明显缩短测量时间。
In addition, the FFT method is immune to the background noise of the signal, so that the process of signal-processing by the FFT method can advanced.
