Answer 1
Yes. Since the requirement for a system to be memoryless is that for any time $ t_0 \in \Re $, $ y(t_0) $ depends only on the input $ x(t_0) $.
In other words, since this system is dependent only on current values of t, not future or past values, we say it is a memoryless system. --Darichar 14:41, 5 February 2011 (UTC)
