LTI Systems and Convolution

Start with signals and system properties

The Signals mind map brings together signal classification, transformations, energy and power, and odd and even signals. It also lists system properties such as linearity, time invariance, stability and causality. Start here if you want a broad view of the terms that appear across the page.

The other mind map covers continuous-time and discrete-time signals, even and odd functions, and properties including memory and causality. A related note presents material from that map in note form.

Move on to flashcards

The LTI flashcards include questions about memoryless, causal and non-causal systems. They also ask about stability conditions for continuous-time and discrete-time linear time-invariant systems. Use them after the maps to check whether you can recall the distinctions.

Other flashcards cover causal and non-causal averages, recursion and impulse response. The convolution cards ask about its purpose and properties, and show steps for an alternative computation approach. You can work through these after reviewing the system-property terms.

Use a quiz alongside a map

The DSP quiz includes a question about an equation involving an input and output, as well as a question about a property of linear systems. Try it after studying the Signals map, then return to the map to review the properties that need another look.

The quiz and map offer different ways to work with the material: the map groups terms together, while the quiz asks you to respond to questions. The flashcards give you another way to check individual concepts.
