Electrical - Essay Example This section explains how to measure the velocity of propagation of a signal in a transmission line. This is done by using the step response method. Also, determining the relative permittivity of the dielectric material used to construct this line, which is based on the measured velocity of propagation. This section focuses on the actions of a transmission line terminated by various resistive load impedances when voltage steps are introduced into the line. Also, checking the characteristic impedance of a line can be carried out by two different methods: (1) with a variable load resistor; or (2) through measurement of the rising edge of the launched step. The definition of attenuation and distortion is provided in this section. The causes of attenuation and distortion, and how they affect the shape of the transmitted signal are also discussed. Finally, evaluating signal quality in high-speed transmission systems by using the eye-pattern method is explained in detail. This instruction booklet gives students the necessary theory and measurement skills to implement and test transmission lines. First, students will learn the principles and operational characteristics of transmission lines. Then, they will discover how to perform transmission line measurements through step testing and a sinusoidal steady-state setting. Lastly, students will build a foundation in theory and practice of time-domain reflectometry (TDR) as well as impedance matching and transformation. Another inclusion is an exercise that focuses solely on troubleshooting. For this exercise, students must establish and recognize the nature of faults introduced by the instructor along the transmission lines through using TDR. This way, students can develop their troubleshooting skills and test what they have learned. – Detailed laboratory procedure where the student
