ET 293B - Telecommunication Transmission Methods

1. Determine parameters such as instantaneous voltage, modulation index, and power distribution in the carrier and upper and lower sidebands and the necessary bandwidth to pass the AM and FM signal using basic and technical math skills.
2. Identify various pulse modulation techniques such as PAM, PCM, PWM, and PPM.
3. Demonstrate a working knowledge of the transmission and reception of serial ASCII and USB functions.
4. State the ISO/OSI 7-Layer Model and give a detailed definition of the importance to the telecommunications (vs. data) field.
5. Distinguish between synchronous and asynchronous (BISYNC, HDLC, and SDLC, etc.) protocols.
6. Specify the best modem transmission system (ie. Cable, DSL, et al.) for various types of telecommunications needs.
7. Explain the differences between FEC and ARQ error correction schemes and identify the syndrome for single bit errors.
8. Use Snell’s Law to determine the critical angle for total reflection in fiber optic cabling and demonstrate a working knowledge of the various grades of fiber and state their advantages and disadvantages.
9. Know the concept of cellular telephony and how it differentiates between land mobile, terrestrial microwave and satellite communications.
10. Calculate a link loss budget on a SONET and on a Microwave transmission path.
