In this paper it is concluded that when the bias point drifts away from the best bias point, CSO (Composite Second Order distortion) is influenced severely, whereas CTB (Composite Triple Beat distortion) is not influenced.

• 通过理论分析得出：当工作点偏离最佳偏置点时，主要对系统的组合二次失真CSO（CompositeSecondOrderdis－tortion）产生影响，并导出相应的公式。
