About Communications, Radar and Optical Systems

GoConqr Original

What this unit covers

This unit sits in the Signals and Communications strand of Electrical and electronic engineering. The resources fall into three groups: modulation and signals, radar, and optical systems. All were made by GoConqr users, so styles and depth vary.

Modulation and signals

The mind map Modulation covers types of modulation, AM power distribution, the modulation index and bandwidth. The mind map Signals shows how information becomes electrical signals, light, radio waves and microwaves. The notes Chapter 3a Amplitude Modulation explain why the baseband signal must be converted for transmission. There are also flashcard decks on Phase Modulation (PM) and Frequency Shift Keying (FSK).

Radar and optical systems

The Radar flashcards ask about angular measurements and the line from the radar set to an object. The quiz 2-1. Radar Fundamentals and the mind map on the continuous-wave radar give a second angle. On the optical side, the mind map Photonic Devices moves from Maxwell's equations and plane waves to Fabry Perot and anti-reflection coatings. The flashcards Chapter 1: Introduction cover fiber optics: core, cladding and total internal reflection.

Where to start

  1. Take the quiz All about Telecommunications for a light check of the basics.
  2. Read the Signals mind map, then Modulation.
  3. Work through the AM notes and the Amplitude Modulation flashcards.
  4. Move on to radar or photonics, depending on your course.

Using quizzes and maps together

Use a mind map to see how the ideas connect. Then test yourself with flashcards, such as the Fourier transform questions in ECE 6390 Exam 2. Quizzes show what you missed, so go back to the map for that branch. Note that some titles are short or personal, so open a resource and check its content before relying on it.

Your next step

Choose one topic from the list, open its map and see how much you can explain without looking. Then make your own flashcards for the gaps.

Frequently asked questions

Which resource should I open first?

Start with the quiz All about Telecommunications. It covers the telephone, 3G and early forms of telecommunication, so it shows quickly what you already know. After that, read the Signals mind map, then the Modulation mind map, before moving to radar or optical topics.

What do the mind maps on this page cover?

There are more than 20 mind maps. They include modulation types and the modulation index, signals and transmission media, photonic devices, pulse characteristics, the continuous-wave radar, 100-Gb/s optical communications and the history of the telephone. Open the one closest to your course topic first.

Are the resources free to use?

Yes. Every resource listed here is free to open, study and take, with no account needed. They were made by GoConqr users rather than by GoConqr itself, so it is worth checking that each one matches your own course material.

Who are these resources for?

Mostly university students and professional candidates who want to go over communications, radar or optics topics. Teachers can use them as ready-made material. A few resources also suit school students. No exam is named in the listed resources.

Where can I practice radar questions?

Try the Radar flashcard deck, which asks about surface angular measurements and the line from the radar set to an object. The quiz 2-1. Radar Fundamentals gives you a further check. The mind map on pulse characteristics helps with the ideas behind both.

What if I can't find my topic?

Not every topic is covered, since the resources come from community members. A free account lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes, so you can fill the gap yourself.
