What is causality in electrical engineering?
The idea that the output of a function at any time depends only on past and present values of input is defined by the property commonly referred to as causality.
What is causality in signal processing?
A system is said to be causal if it does not respond before the input is applied. In other words, in a causal system, the output at any time depends only on the values of the input signal up to and including that time and does not depend on the future values of the input.
What is the importance of causality in DSP?
Here, for the system to be causal, it should be independent from the future values only. That means past dependency will cause no problem for the system from becoming causal. Causal systems are practically or physically realizable system.
