Signals and systems/System properties
- Systems with memory/without memory
- Casual systems
- Stable systems
- Time invariance in systems
- Linearity in systems
Memory in systems edit
When no need to maintain previous values for getting new results - this is memoryless system
Casuality of systems edit
Output depends only from past and current inputs, but no need to know future values.
Stable system edit
For 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 edit
When then
Expected results for all reasonable inputs.
