Signals and systems/System properties
- Systems with memory/without memory
- Casual systems
- Stable systems
- Time invariance in systems
- Linearity in systems
Memory in systems
editWhen no need to maintain previous values for getting new results - this is memoryless system
Casuality of systems
editOutput depends only from past and current inputs, but no need to know future values.
Stable system
editFor each bounded inputs - bounded outputs. When finite inputs then finite outputs.
Time invariance
edit and
Expected results when time is changing by delta.
Linearity systems
editWhen then
Expected results for all reasonable inputs.
