stream transformer

Show Summary Details

Quick Reference

A function that maps streams to streams. If [TA] is the set of all streams of elements of set A indexed by time T then, for example, a stream transformer that maps a pair of streams into one stream is a function of the form

F : [TA]2 → [TA]

Stream transformers are often defined in the equivalent but logically simpler form

G : [TA]n × TA

where G(a,t) = F(a)(t) for stream a and time t, i.e. G(a,t) is the element on the output stream F(a) at time t.
