25.2px;">交流通路和</span><span style="line-height: 1.8em;">直流通路。</span><span style="line-height: 25.2px;">交流电路是指交流信号传送的途径，即交流信号的来龙去脉。</span><span style="line-height: 1.8em;">直流通路是指在没有输入信号时，各<a href="http://sensor.oecr.com" target="_blank" class="relatedlink">半导体</a>三极管、集成电路的静态偏置，也就是它们的静态工作点。</span><span style="line-height: 1.8em;">在实际电路中，交流电路与直流电路共存于同一电路中，它们既相互联系，又互相区别。</span></div><div><span style="line-height: 1.8em;"><br></span></div><div> <font color="#f00000"><b>什么是直流等效分析法</b></font></div><div><br></div><div> 直流等效分析法，就是对被分析的电路的直流系统进行单独分析的一种方法，在进行直流等效分析时，完全不考虑电路对输入交流信号的处理功能，只考虑由电源直流电压直接引起的静态直流电流、电压以及它们之间的相互关系。<span style="line-height: 1.8em;">直流等效分析时，首先应绘出直流等效电路图。绘制直流等效电路图时应遵循以下原则：电容器一律按开路处理，能忽略直流电阻的电感器应视为短路，不能忽略电阻成分的电感器可等效为电阻。取降压退耦后的电压作为等效电路的供电电压;把反偏状态的半导体二极管视为开路。</span></div><div><span style="line-height:
