A symbolic notation is used to describe the drivingpoint immittances measured at either port of an unbalanced two-port ladder network containing two kinds of elements LC, RC, or RL. It is shown that using this notation, distinctive letter symbols with indices together with operator symbols, and by applying some logical rules, the relationship between input and output immittances, between dual and between identical ladders becomes very simple. The symbolic notation is more descriptive and pictorial in the light of circuit theory than the correlated mathematical formulations. The article is a first attempt to apply logical considerations to circuit problems and wants to give some stimulation for further studies in this direction. Author
