分享一些电子工程相关英语句子。 1.Consider what we know intuitively about an integrator. If you apply a DC signal at the input (i.e. , zero frequency), the output will describe a linear ramp that grows in amplitude until limited by the power supplies. Ignoring that limitation, the response of an integrator at zero frequency is infinite, which means that it has a pole at zero frequency. (A pole exists at any frequency for which the transfer function’s value becomes infinite.) 1.我们怎么从直观上理解积分器呢?假设在输入端加上一个直流信号(频率为0),那么在输出端将会出现一个线性斜坡信号,其幅度一直增至电源电压。如果不考虑电源电压对输出信号的限制,积分器在零频率上的响应将是无穷大,这意味着它在零频率点上存在一个极点(在任何使传递函数为无穷大值的频率点上都存在一个极点)。 2.While the complex frequency’s imaginary part helps describe a response to AC signals, the real part helps describe a circuit’s transient response. 2.复频率的虚部有助于描述电路对交流信号的响应,而其实部有助于描述电路的瞬态响应。 3.The low-pass filter’s transient response is more stable, because its pole is in the negative-real half of the complex plane. 3.低通滤波器的瞬态响应更加稳定,因为其极点位于复平面的左半部。 |
