被动组件 Passivity (engineering)

（重定向自Active device）

被动组件（Passive components）在不同领域有不太一样的定义，它是电子组件的类型之一。被定义为在工作时间内，不能供应任何平均值大于零的功率到外界的电子组件。例如电阻，将功率的消耗转化为热能。

E_A(x)=\sup_{x \to T \geq 0} \int_0^T -\langle v(t),i(t)\rangle \, \mathord{\operatorname{d}}t
  • T≥0
  • 功率为\langle v(t),i(t)\rangle，即v(t)与i(t)的内积

Passivity (engineering) 被动元件

（重定向自Active device）
Television signal splitter consisting of a passive high-pass filter (left) and a passive low-pass filter (right). The antenna is connected to the screw terminals to the left of center.

Passivity is a property of engineering systems, used in a variety of engineering disciplines, but most commonly found in analog electronics and control systems. A passive component, depending on field, may be either a component that consumes (but does not produce) energy (thermodynamic passivity), or a component that is incapable of power gain (incremental passivity).
