可编程逻辑 HDB3编解码器设计
HDB3(High Density Bipolar三阶高密度双极性)码是在AMI码的基础上改进的一种双极性归零码,它除具有AMI码功率谱中无直流分量,可进行差错自检等优点外,还克服了AMI码当信息中出现连“0”码时定时提取困难的缺点,而且HDB3码频谱能量主要集中在基波频率以下,占用频带较窄,是ITU-TG.703推荐的PCM基群、二次群和 ...

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 ...
