One of the main uses of Thevenin's and Norton's theorems is the replacement of a large part of network very simple equivalent

6.1选择合适的答案填入空内。 (1)对于放大电路,所谓开环是指 A.无信号源 B.无反馈通路 C.无电源 D.无负载

The series combination of voltage sources: Several voltage sources in series may be replaced by an equivalent voltage source having a voltage equal to the algebraic sum of the individual sources

Ohm's law states that voltage across many types of conducting materials is directly proportional to the current flowing through the material. U= Ri or R= i R--resis tance()( linear resistor) The resistor is a passive element that cannot deliver power or store energy

7.1.1在图题7.1.1所示的各电路中,哪些元件组成了级间反馈通路?它们所引入的反馈 是正反馈还是负反馈?是直流反馈还是交流反馈?(设各电路中电容的容抗对交流信号均可忽 略) 解图题7.1.1a中,由电阻R2、R1组成反馈通路引入负反馈,交、直流反馈均有;b图中, 由R引入负反馈,交、直流反馈均有,由Rn、Rn引入直流负反馈;c图中,由R1、R2引入负反 馈

We assume=Im cos(t+a)i=Im cos(ot+B) The phase angle by which the voltage leads
