The proposed signal transmission system consists of a low cost duty-cycle modulation circuit, a transmission line model and a linear demodulator. The study of the signal transmission system is conducted using analytical developments and virtual simulation models. Then, the results obtained under a variety of modulating waveforms including standard signals and arbitrary waveforms, show the high quality of the proposed duty-cycle modulation scheme for signal transmission systems. http://pubs.sciepub.com/ajeee/2/3/4/ajeee-2-3-4.pdf modeling Duty-Cycle-Modulation lossless transmission line Low-Pass Filter simulation
