EET 130 - Introduction to Telecommunications
3 Lecture Hours 2 Lab Hours
Co-requisites: EET 103
This course provides an overview of basic principles of electronic circuits and their applications to telecommunications. Topics include amplifier circuits and analysis, audio circuits, tuned Radio Frequency (RF) amplifiers, oscillator circuits, receiver circuits and AM and FM modulation. Microwave and satellite communications are introduced.
Upon successful completion of the course, the student will:
- Analyze series and parallel resonant circuits by calculating resonant frequencies.
- Describe electromagnetic radiation and the concept of a carrier.
- Explain the function of a tuner and how it receives different frequencies.
- Demonstrate the operation of an oscilloscope and spectrum analyzer.
- Explain amplitude, frequency and phase modulation and the techniques of modulation and demodulation.
- Describe pulse communications techniques and frequency division multiplexing.
- Describe the process of communications in a shared medium, including carrier sense multiple access with collision detection.
- Measure energy loss of the fiber optic cable.
- Explain the concepts of fiber optics and laser technology.
- Construct a radio detector for amplitude modulation and frequency modulation using transistors and integrated circuits.
- Explain how regulations impact the technical function of communications systems in both licensed and unlicensed environments.
- Apply appropriate operating procedures for amateur radio in compliance with a Federal Communications Commissions Technician class license.
