- 三点式振荡器是指LC回路的三个端点与晶体管的三个电极分别连接而成的电路，如图4-1（a）所示。图中三个电抗元件X1、X2、X3构成了决定振荡频率的并联谐振回路，同时也构成了正反馈所需的反馈网络。从相位条件看，要构成振荡器，必须满足： (1)极相连的两个电抗X1、X2性质相同。 (2)X1与X2、X3的电抗性质相反。-three-point refers to LC oscillator circuit with three transistors endpoint of three electr
chase2decoding
- 对分组码的chase2译码算法比较与硬判决，未编码情况下的提高了误码率增加了编码增益-right to a code decoding algorithm chase2 compared with the hard decision, no coding of the increased bit error rate increased coding gain
