图2:单位脉冲序列 \delta[n] 的数学定义够简单,图形够直观,仅当 n=0 时,序列的幅值为1(所以称为单位脉冲), n\ne 0 ,幅值为0。 \delta[n] 是信号与系统中最简单的信号,但它的重要性却不可小觑。 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 , &...
The addition output of the adder 14 gives a value corresponding to the total sum of the charging voltages of the respective condensers, and this is displayed by a display unit 15.doi:10.1109/ppps.2001.1001778YASUDA MASARUSHIOMI HISANOBU

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...

On this basis, individual impulse response func- tions are introduced for each pair of input channel l and output channel m, yielding the complete description Table 1 Real-Valued Spherical Harmonics Used as Spatial Basis Functions Nr Spherical harmonic 0: 1 1: x 2: y 3: z 4: xy 5: zy...
The arrangement has a monitoring unit (11) for monitoring an output voltage of a secure output stage (3), where the monitoring unit is activatable in coincidence to the sampling of the secure output stage. The monitoring unit generates a response impulse if the output voltage of the secure ou...

The filling valve and the empty valve are controlled by a control unit (29) in an impulse form. 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 ...
Accordingly, another rapper unit may be employed to drive the structure in a different response mode, or may drive the structure such that the areas of maximum and minimum deflection are repositioned to thereby provide adequate ash removal. While the above description constitutes the preferred ...
