The switching devices whose outputs are essentially d—c levels, and which can be switched from one state to the other at any arbitrary instant. The devices can be switched as seldom or as often as desired, up to a certain maximum speed. However, once they are switched to one state or the other, they are capable of remaining in that state indefinitely, and the output signal will be a d—c level. A typical example of a static circuit element is the flipflop or a stable multivibrator.; 用于指輸出基本是直流電平可在任一時(shí)刻從一種狀態(tài)轉(zhuǎn)換至另一種狀態(tài)的開(kāi)關(guān)器件。該器件可根據(jù)需要很少或經(jīng)常轉(zhuǎn)換,直到某個(gè)最 高速度。然而一旦轉(zhuǎn)換到一種狀態(tài)或另一種狀態(tài),則可以長(zhǎng)期保持這種狀態(tài),輸出信號(hào)將為一直流電平。靜 態(tài)電路元件的一個(gè)典型例子是觸發(fā)器或穩(wěn)態(tài)多諧振蕩器。
