2声频系统设备的输出波形2.1设备输出电路的输出特性与负载线输出电路的输出特性取决于输出电路的“工作点”和“负载线”的设计,放大器空载时的工作点和负载线称为直流工作点和直流负载线,放大器有载时的工作点和负载线称为交流工作点和交流负载线,下面进行一些分析。 2 audio system equipment output waveform 2.1 device output circuit output characteristics and load line output circuit output characteristics of the output circuit depends on the “working point ” and “load line ” design, the amplifier no-load operating point And the load line is called the DC working point and the DC load line. When the amplifier is loaded, the working point and the load line are called the AC working point and the AC load line. Some analyzes are given below.
