negative feedback amplification
Examples
- The stability of feedback of amplifier circuit is often analyzed with bode in " simulation electron and technology " in the advanced institutes
摘要目前高等院校在模拟电子技术课程中对于负反馈放大电路稳定性进行分析时，一般采用波特图的分析方法。 - Here this article describes and analyses the general charts of several multi - loop negative feedback amplifying circuits and the general formula of the " closed - loop " amplifying ( transfer function )
给出几种多环负反馈放大电路的一般方框图和“闭环”增益（传输函数）一般表达式，并浅析。 - Basde on further , analysis of formula d = 1 - af , this paper points out the conflict when using instantaneous limit and jadging positire and negative feedbavk byusing the depth of peedbavk , range of middle freguency of pnegative feedback amp circuit can also appear self - conflitct
摘要通过对公式d = 1 - af的进一步分析，指出用瞬时极性法与用反馈深度判定正负反馈时所出现的矛盾，说明负反馈放大电路的中频段也会出现自激的情况。 - The actual negative feedback amplifying circuit doesn ' t form a closed - loop only from the basic amplifying circuit and the feedback network , but forms the multi - loop system ( multi - loop negative feedback circuit ) from several basic amplifying circuits and several feedback networks
摘要实际的负反馈放大电路，并非都是由基本放大电路和反馈网络构成一个闭环系统< 1 > ，还有由多个基本放大电路和多个反馈网络构成的多环系统（多环负反馈电路） < 2 > 。
