The Heaviside condition, named for Oliver Heaviside (1850–1925), is the condition an electrical transmission line must meet in order for there to be no distortion of a transmitted signal. Also known as the distortionless condition, it can be used to improve the performance of a transmission line by adding loading to the cable. ==The condition== A transmission line can be represented as a distributed element model of its primary line constants as shown in the figure. The primary constants are the electrical properties of the cable per unit length and are: capacitance ''C'' (in farads per meter), inductance ''L'' (in henries per meter), series resistance ''R'' (in ohms per meter), and shunt conductance ''G'' (in siemens per meter). The series resistance and shunt conductivity cause losses in the line; for an ideal transmission line, . The Heaviside condition is satisfied when : This condition is for no distortion, but not for no loss. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heaviside condition」の詳細全文を読む スポンサード リンク
