Method and system for simulation of frequency response effeccts on a transmission line due to coupling to a second electrical network by direct synthesis of nulls

A system for simulating the effect of an unterminated transmission line coupled to a transmission line at an intermediate point comprising:

• a central processing unit (“CPU”), wherein the CPU is adapted to:
• (a) receive as input a resistance per unit length of an unterminated transmission line parameter (R), a capacitance per unit length of an unterminated transmission line parameter (C), an inductance per unit length of an unterminated transmission line parameter (L) and a conductance per unit length of an unterminated transmission line parameter (G), a characteristic impedance of a transmission line parameter (Z0) and a length parameter (d);
• (b) determine an input impedance of the unterminated transmission line as a function C, R, L, G, Z0 and d;
• (c) determining a frequency response of the unterminated transmission line coupled to the transmission line in a shunt configuration as a function of the input impedance of the unterminated transmission line and the characteristic impedance of the transmission line;
• (d) determining a circuit having the frequency response approximating the frequency response in step (c).
