PCB Transmission Line Quiz

by | Mar 9, 2018 | 9 comments

A PCB transmission line is a type of interconnection used for moving signals from their transmitters to their receivers on a printed circuits board. They are very complex to understand, which is why we created this quiz. Find out how much you know about PCB transmission lines!

 

Results

Congratulations, you know a lot about PCB transmission lines! Why don’t you give us your feedback on our PCB Transmission Line eBook?

It looks like you still have one thing or two to learn about PCB transmission lines! download our PCB Transmission Line eBook and take the quiz again. You will definitely pass this time!

next

#1. How many conductors does a PCB transmission line usually contain?

next

#2. Name the conductors referred to in the last question.

next

#3. What is the volume between the two conductors?

next

#4. Why do transmission lines need to have a controlled impedance at high frequencies?

next

#5. Electromagnetic signals travel in vacuum or air at the same speed as of light. Why do signals travel on PCB transmission lines at a slower speed?

next

#6. What does “tpd” refer to?

next

#7. What is the propagation delay?

next

#8. What is approximately the signal speed for Isola 370HR materials on a stripline?

next

    unfortunately I could not see the pictures on firefox on linux. Thus I could not answer two questions. But fun it was

    Broken link? There is no button to click to start the quiz, that I could find. The closest thing was this cryptic text between the text below the picture and the two links to other articles:
    [HDquiz quiz = "772"]

    Is that supposed to be a button?

    Of course, specially Low voltage signal lines! It needs low resistance passage way point to point!

    I got 8 of 9 right — but I have an issue with #1. The transmission line itself is 1 conductor — the return path is a second conductor.
