Modulation in Communication System for RF Engineers RAHRF152

This course provides a second certificate completion for FREE from Rahsoft Introduction to Modulation in Communication Systems RAHRF152 is an intro course of Rahsoft Radio Frequency Certificate and it is counted toward the certificate. In this course we have concentrated to simplify the Digital and Analog Modulation topics in a way which students would understand the practicality by providing examples and simulations using GNU Octave open source software. This is a great course to understand the fundamental definitions needed in digital and analog modulation in communication system.
