A .plot command appears in the SPICE netlist, and normally this would result in a sine-wave graph output. In this case, however, I've purposely omitted the waveform display for brevity's sake -- the .plot command is in the netlist simply to satisfy a quirk of SPICE's Fourier transform function.
No discrete Fourier transform is perfect, and so we see very small harmonic currents indicated (in the pico-amp range!) for all frequencies up to the 9th harmonic, which is as far as SPICE goes in performing Fourier analysis. We show 0.1198 amps (1.198E-01) for the "fourier component" of the 1st harmonic, or the fundamental frequency, which is our expected load current: about 120 mA, given a source voltage of 120 volts and a load resistance of 1 kΩ.
Next, I'd like to simulate a nonlinear load so as to generate harmonic currents. This can be done in two fundamentally different ways. One way is to design a load using nonlinear components such as diodes or othe

积香料网表出现在指挥,这通常会导致一种正弦波输出图形.不过,在这件事,我故意省略了波形显示简洁起见--. 积指挥是单纯的网表满足了香料论Quirk的傅立叶变换功能.没有离散傅里叶变换是完美的,所以我们看到非常小的谐波电流显示(在微微安培射程!) 所有班次多达九谐,而据香料搞表演傅立叶分析.我们拿专0.1198(1.198e-01)为"傅立叶分量"一号谐,或根本频率这是我们预料负载电流:约120马有120伏特的电压源和一个电阻负荷kω1.接下来,我想以模拟非线性负荷谐波电流产生.这可以在两个截然不同的方式.其中一个方法是设计一个利用非线性负荷或其它部件,如半导体二极管模拟装置容易与香料.另一部分是将交流电流源与负载电阻并联.后者往往是首选的方法模拟工程师谐波、由于目前已知源本身价值更好地与数学网络构成比分析高度复杂反应特征.既然我们所做的一切,让香料数学工作复杂的半导体组件造成任何麻烦,但由于目前能源微调出示任意金额电流(便捷专题)我永远选择后者:
