  • 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 ...

  • 基于ICL8038等构成的函数发生器电路

    摘要:本系统以ICL8038集成块为核心器件,制作一种函数信号发生器,制作成本较低。适合学生学习电子技术测量使用。ICL8038是一种具有多种波形输出的精密振荡集成电路,只需要个别的外部元件就能产生从0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脉冲信号。输出波形的频率和占空比还可以由电流或电阻控制。另外由于该芯 ...
