Розроблення віртуального лабораторного практикуму для дистанційного дослідження цифрових систем передавання в системі Moodle

In this paper the development of emulation of digital transmission systems for the study of basic transformations that is undergoing speech signal in a transmission system with time multiplexing and pulse code modulation with imaging findings. Analyzed the feasibility of using virtual simulator in the study subjects “Telecommunication transmission systems” for students training “Telecommunications” and test control of learning material.
