This laboratory course supports the Wireline and Wireless Telecommunications Engineering course (EET-478). The experiments include T1 testing, QPSK/QAM generation, bit error rate testing, CDMA and TDMA generation, operation of a PBX switch, microwave link testing, TDR testing. The hands-on experience on the instrumentation used in the industry such as Spectrum Analyzers, Network Analyzers, RF Signal Generators and T1 Tester is planned in this course. The computer simulation and the wire-wrapping circuits are used minimally. (Prerequisite or Corequisite EET-478)

Radio Engineering III Laboratory Exercise

Measurement of Refractive Index of Glass

Introduction

This is a very simple experiment that can provide insight into the electromagnetic wave propagation and fibre optics. The experiment requires minimal equipment, and it does not require power supplies, batteries or a computer.

Learning Objectives

At the end of this experiment; by use of the equations provided in the appendix and Fig 1, one should be able to do the following:

• Measure angle of incidence
• Measure angle of refraction
• Determine refractive index of glass
• Verify Snell's law
• Calculate the critical angle
• Calculate wave impedance of air
• Calculate wave impedance of glass
• Calculate input relection coefficient from air to glass
• Calculate return loss
• Calculate transmission coefficient from air to glass
• Calculate velocity of propagation of light in air
• Calculate velocity of propagation of light in glass
• Calculate VSWR (voltage standing wave ratio)
  

Filter Response

Objective

To show how a spectrum analyzer can be used to quickly determine the response of a filter.
