Fork

Specifications

A Fork has one input terminal and two output terminals. Every input signal produces a signal on both output terminals.

Specification in Verdect:


define F( a?, b!, c! ) =
       pref *[ a?; (b! || c!) ]
end

Specification in DI Algebra:

NAME = fork
I = {a?}
O = {b!, c!}

F = a?;b!;c!;F

The roles of outputs b and c can be interchanged:
F(a; b, c) = F(a; c, b)

The Fork can be generalized to , which forks to k outputs (k>0). A Fork is a 2-Fork.

In [Ornstein67, p. 344], the Fork is referred to as Control Branch.

In [Ebergen89, Section 2.2.4, p. 31], the Fork is referred to as FORK component.

Something about isochronic Forks, symmetric, asymmetric...
