笔记 音频放大器设计
This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor.
Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant) 
Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)] 
Use Coupling ...

%this is an example demonstrating the Radial Basis Function
%if you select a RBF that supports it (Gausian, or 1st or 3rd order
%polyharmonic spline), this also calculates a line integral between two
%points.
