Abstract: In this work, element value calculation algorithms have been proposed for low-pass, high-pass, band-pass and band-stop LC ladder networks. According to the calculated constant from the given transfer scattering matrix, the element type that will be extracted is decided. After calculating the element value, its transfer scattering matrix is obtained. Then transfer scattering matrix of the remaining network is calculated and the same procedure is applied until the termination resistance is reached. After explaining the algorithms, four examples are given to illustrate the utilization of the proposed method. Keywords: Decomposition, LC Ladder Networks, Lossless Networks, Transfer Scattering Matrix.
