discrete-time signals造句
例句与造句
- The theory of soplat using frequency rate is discussed in chapter 2 . based on this theory , this chapter studies the observed discrete - time signal . the crlb of continuous wave and coherent pulses frequency estimation are also studied
论文第二章讨论了利用频率变化率的单站无源定位原理,在此基础上,介绍了单站无源系统中接收信号的模型,并分析基于各模型的频率估计的cramer - rao下界。 - Contrasting this , in feedback control the most majority of complex systems are controlled using sampled observations of system behavior taken at discrete time instants . thus the resulting controlled systems are hybrid systems , which are called sampled - data systems , involving both continuous - time and discrete - time signals . the investigation of sampled - data systems is motivated primarily due to the widespread use of digitally implemented controller in present - day feedback control of continuous - time systems
工程实践中遇到的动态系统通常是连续时间系统，与此相反，大多数复杂系统的反馈控制却是通过观察采样点上的系统行为来进行控制的，结果所得到的反馈控制系统是个混合系统，它含有连续信号和离散信号，这样的系统称之为采样系统，当今连续受控系统中数字控制器的广泛运用促进了对采样系统的研究，已有的线性采样系统理论显然不能满足处理非线性采样系统的需要，因此近年来非线性采样系统的分析与设计已经成为国际控制论界的持续的研究热点之一。 - It's difficult to find discrete-time signals in a sentence. 用discrete-time signals造句挺难的
