Communication System Modulation concentrated to simplify the Digital and Analog Modulation topics in a way which students would understand

Requirements

  • Basic Engineering level math and willingness to learn the demanding topic of modulation in communication.

Description

Communication System RAHRF152 is an intro course of the 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 in 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.
