接下来介绍稍复杂一点的单位阶跃(unit step)序列 u[n] ,定义为: u[n] = \begin{cases} 1 , & n \ge 0 \\ 0, & n < 0 \end{cases} \\ \tag{2} 对应的图形为: 图3:单位阶跃序列 我们尝试用最简单的 \delta[n] 通过信号运算来得到稍复杂一点的 u[n] 。回顾一下,到目前为止,我们掌握的...
An impulse unit having a variable torque output and suitable for use in an impulse tool having a housing and a motor, is rotatably mounted in the tool housing and driven by the tool motor. The impulse unit comprises a casing assembly having an impulse cavity therein which is filled with a...
在本讲中，我们将深入探讨信号与系统领域中的两个基本概念：单位脉冲与单位阶跃函数。这些概念在实际应用中尤为重要，帮助我们理解系统性能并进行测试。以买西瓜为例，通过敲击来判断西瓜的成熟度，实际上是应用了单位脉冲信号的思想。在乐器店，用锣或鼓的击打声来评估乐器质量，这一行为同样体现了单位脉...

FIG. 3 is a side elevational view of a rapper according to a third embodiment of this invention particularly adapted for removing slag and encrustations from wall tubes of a boiler; FIG. 4 is a top view of the rapper shown in FIG. 3; FIG. 5 is a side elevational view of a rapp...
The control unit determines opening and closing times of the filling valve and/or the empty valve based on pressure of the supplied cold water. The supply line ends in an opening. Independent claims are also included for the following: (1) a method for refilling a steam producer of a ...
Impulse-radio millimeter-band transmission equipment was developed using the aforementioned technologies, which included a baseband unit with a fiber-optic interface. The receiver had a sensitivity of 0.25 microwatts (0.25 µW), and along with the sensitivity needed for kilometer-class wireless transm...
Remark 1.3.5 Definition1.3.3singles out strategies that share the same symmetry line with the game. For the linear game, for example, the authors find infinitely many NEs [1, Prop.4.7], each presenting symmetry with respect to some points, but only one for\(s=0\)(hence, symmetric in ...
