4.1/5

## Modulation in Communication System for RF Engineers RAHRF152

### What you’ll learn

have a practical understanding of Modulation concepts.
Rather than knowing formulas students will be able to actually talk about different concepts if modulation

### Requirements

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

### Description

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.
