I read that the electrical properties of transmission lines can be described using their RLCG parameters (line resistance, inductance, capacitance and dielectric conductance per unit length).
How can one elegantly introduce "noise" to transmission lines, so that their properties vary within a given interval, ie +-100 Ohms, +-100uH,
+-100pF ... ? Would one use a combination of controlled resistors (ie JFETs), inductors and varactors or is there a simpler solution?It would also be sufficient if one could adjust those parameters specifically (ie. add 10 Ohms, subtract 10pF)
Thank you! Tobias
