Expand description
Trait for causal systems.
Background:
A causal filter is a filter with output and internal states that depends only on the current and previous input values.
Contrarily a system that has some dependence on input values from the future (in addition to possible past or current input values) is termed an acausal system, and a system that depends solely on future input values is an anticausal system. Wikipedia
