Use of the Valve Equivalent Circuit,re than one valve is used in the circuit. The problem is further complicated by the presence of reactive components which may affect the performance at certain operating frequencies. Chapter 3 showed that valves could be represented by equivalent circuits. The circuits developed were suitable for smGORGE 发表于 2025-3-23 21:15:03
Use of Transistor Equivalent Circuits,ivalent . were shown to be suitable for representing the transistor. It must be stressed that the component values for such circuits will only apply at a particular d.c. operating point and that there may be considerable variation in these values for transistors of nominally the same type. It is appfleeting 发表于 2025-3-24 00:53:01

Modifications to Equivalent Circuits for High Frequency Operation, effects of the various reactances associated with the construction of valves and transistors, and the transit time for which the electrons or holes are crossing the active region of the device. The reactances are due to capacitance between the various electrodes and to lead inductance. If the trans花争吵 发表于 2025-3-24 10:49:08
