## Catalog Description

Communications Electronics develops the knowledge and ability to design communication electronics, such as AM/FM radios using transistors and integrated circuits. This course applies the concepts of circuits and electronics to basic analog communication circuits for amplitude and frequency modulation. Topics studied are RF Amplifiers, Fourier Analysis, AM and FM transmission and reception, phase-locked loops, synthesizers, oscillators, DSB and SSB communication systems, antennas, and EM wave propagation. The course’s laboratory component provides experience in the practice and application of the concepts of circuits and electronics to basic analog communication circuits for amplitude and frequency modulation in a laboratory environment. Construction and measurement are emphasized.

## Course Overview

- This course focuses on both traditional analog circuitry used in communications electronics as well as more modern software defined radio methods.
- Traditional modulation methods such as AM and FM are explored as well as digital modulation techniques.
- Students will use extensive circuit simulation to verify design of circuits prior to building working prototypes
- Students will learn how to prototype, debug and measure RF circuits using typical equipment found in industry.
- Elements of communications technologies are used in a wide variety of new and emerging technologies such as wireless communications and the internet of Things (IoT)

## Course Learning Outcomes

By the end of this course you will be able to:

- Identify the key components and functions of an electronic communications system
- Describe how information is transmitter and received via different media
- Decompose complex periodic signals into its Fourier components
- Design an active filter using op-amps and a passive filter using reactive components
- Identify different oscillator configurations. Build an oscillator to generate an RF carrier signal
- Describe the fundamental aspects of AM, FM and Phase modulation. Build and test an AM and FM modulator.
- Describe the operation of an IQ modulator and demodulator, a fundamental component in software defined radios
- Compute signal and noise levels in a cascaded RF system. Compute noise levels based on input thermal noise and cascaded noise figure of a system

## Teaching Philosophy

In class lectures will present the main topics for the course. In class activities are used to support learning and understanding of concepts. The laboratory exercises combine simulation and the practical aspects of building and testing prototypes.
