Classify Signals (Static vs Dynamic) Homework Assignment
A system is static iff the output at time t depends only on the input at time t
A system is dynamic iff the output at time t depends on the input at time t as well as the input at other times (i.e. in the past or future)
A system is causal iff the output at time t depends only on the the input at times at or before time t (i.e. not future values of the input)
A system is anti-causal if its output depends on the input at times after time t.
