ET 293 - Telecommunication Transmission Methods


Credits: 3
Description
Topics include: Amplitude, Frequency and Pulse Modulation, Modem technologies (wireline, cable and DSL), error control, cyclic codes (CRC-16, Hamming, etc.). Circuit switched and packet transmission of voice and data over SONET and wireless media (fiber optic and microwave) are emphasized.

Student Learning Outcomes
  1. Use technical math skills to calculate and analyze instantaneous voltage, modulation index, power distribution in the carrier and sidebands, and the bandwidth required to transmit AM and FM signals.
  2. Identify and differentiate various pulse-modulation techniques such as PAM, PCM, PWM, and PPM.
  3. Analyze and explain the transmission and reception processes of serial ASCII and USB communication functions.
  4. State, interpret, and evaluate the importance of the ISO/OSI 7-Layer Model to the telecommunications field.
  5. Distinguish and compare synchronous and asynchronous protocols, including BISYNC, HDLC, and SDLC.
  6. Evaluate and specify the most appropriate modem transmission system (e.g., Cable, DSL, etc.) for a given telecommunications application.
  7. Explain and compare FEC and ARQ error-correction schemes to identify the syndrome corresponding to single-bit errors.
  8. Use Snell’s Law to determine the critical angle for total internal reflection in fiber-optic cabling multiple slots in one.
  9. Analyze and compare various fiber grades.
  10. Explain and analyze the concepts of cellular telephony to differentiate it from land-mobile, terrestrial microwave, and satellite communications.
  11. Calculate and verify link-loss budgets for SONET and microwave transmission paths.
