一、概述:同轴电缆的设计中,有一个重要的电气参数是电缆单位长度的电容 C。它在传输脉冲信号时显得特别重要,为了减少信号波形的畸变,要求电缆具有尽可能低的电容.电缆电容的变化还会引起电缆特性阻抗的变化,所以电缆的电容参数就显得十分重要了。对于同轴电缆的 First, an overview: coaxial cable design, there is an important electrical parameter is the cable length of the capacitor C. It is very important when transmitting pulse signal, in order to reduce the distortion of the signal waveform, it is required that the cable has the lowest possible capacitance. The change of the cable capacitance also causes the change of the characteristic impedance of the cable, so the capacitance parameter of the cable becomes very important. For the coaxial cable
