About Signals, Systems and Signal Processing
GoConqr OriginalWhat the resources cover
The page opens with the foundations. The mind map Signals and Systems defines a signal as a function carrying information, and a system as an entity that extracts useful information from it or processes it. The EE222 mind map goes on to even and odd functions, continuous-time and discrete-time signals, and static and dynamic systems. The Signals mind map covers linearity, time invariance, stability, causality, invertibility, energy and power.
Moving on to transforms and filters
Once the basics are clear, the Digital Filter mind map covers FIR and IIR filters, impulse response, direct, cascaded and polyphase forms, DFT, DTFT and aliasing. The mind map on Fourier analysis covers Fourier series, Fourier coefficients, and amplitude and phase spectra. There are also flashcard decks titled Fourier Transforms, Dirac Delta and LTI.
Beyond the core topics
Some resources reach into applications. The mind map on on-board data processing for downlink optimisation looks at data compression and FPGA implementation. The slide set Video Coding Fundamentals and the mind map MPEG2 vs H.264 deal with video coding. The IVC flashcards cover how human vision responds to contrast, luminance and spatial frequency.
A sensible order
- Start with the mind map Signals and Systems and the EE222_Section1 flashcards for the vocabulary.
- Move to the Signals mind map for system properties.
- Try the quiz Introduction to Continuous and Discrete-Time Signals and Systems.
- Read the Fourier and filter maps, then take the Fourier Series quiz and the Filter and Signal Processing quiz.
Use maps to see how ideas connect, then quizzes to find what hasn't stuck. Return to the map for any topic you miss.
Where it fits
This unit sits in the Signals and Communications strand of Electrical and electronic engineering. Pick one map, try one quiz, and see where your gaps are.
Frequently asked questions
Which resource should I open first?
Start with the mind map Signals and Systems. It defines a signal and a system in plain terms, so the later material makes more sense. The EE222_Section1 flashcards are a good second step, as they drill the basic vocabulary of continuous-time and discrete-time signals.
What do the mind maps cover?
They range from basic signal classification, such as even and odd signals, energy and power, to system properties like linearity, causality and stability. Others cover Fourier analysis, digital filters, data compression and video coding. There are 24 mind maps on the page, made by community contributors.
Which quizzes are available?
There are more than 10 quizzes. Examples include Fourier Series, Introduction to Continuous and Discrete-Time Signals and Systems, Filter and Signal Processing, and two on digital signal processing. Use them after reading a map to see which topics need another look.
Who are these resources for?
They are mostly aimed at university students, who can use them to revise topics and check their understanding. Teachers can also use them as ready-made material. The resources were made by GoConqr users, not by GoConqr itself, so it is worth checking them against your own course notes.
Are the resources free to use?
Yes. Every resource listed here is free to open, study and take, with no account needed. If you want to save quiz scores or make your own quizzes, mind maps, flashcards and notes, you can add a free account.
What if the topic I need is missing?
Look at related titles first, since topics often sit inside broader maps, such as sampling within the digital signal decks. If it still isn't there, you can make your own mind map or flashcards on it, and your own material is easy to build once you have an account.
