单频信号 meaning in English
simple signal
Examples
- Most of the literatures considering analog input are focused on simple harmonic input , because the output waveform from a bistable system is greatly distorted
同时，对于模拟信号输入的情况，大部分已有的结果都是集中在单频信号上的，这主要是由于双稳态系统的输出有严重的波形畸变。 - As for single harmonic input , the output information can be easily retrieved by some typical methods , such as frequency analysis and a bandpass filter . but when treating a multi - frequency analog signal , there is not a simple method
对于单频信号可以很好的利用频谱特性进行检测，或者通过带通滤波器进行处理，但是对于多频信号，没有很简单的方法。 - Based on chaos critical state detection method , two approaches are used : one is that making a pretreatment on dsss signal to take out the period information of the signal . the other is that starting from the analysis of the sensitivity of duffing system to ambi - polar square wave modulated by sine signal , the
通过两种途径:对信号进行预处理,提取出其中的周期信息,转化为单频信号检测;从研究duffing振子对方波调制信号的敏感性出发,全面分析其中的间歇混沌现象,实现信噪比- 20db以下dsss信号的检测。 - Based on classification of general jamming signal , generalizing them and analyzing their performance , the effectiveness of the pressing jamming and interference is deeply studied . the optimal jamming bandwidth of the wideband white noise and the optimal jamming frequency of the single sinusoidal signal are deduced by theoretical analysis and detailed derivation
在对常用干扰方式进行分类、概括性总结及特点分析的基础上,深入研究了直扩通信系统压制式干扰效能,并通过理论分析和详细推证,得到了宽带噪声信号最佳干扰带宽和单频信号最佳干扰频率。
