Spectrum
From Organic Design wiki
In the nodal model, the spectrum is the set of cycles used by the network. Each instance of a cycle is globally available and accurately synchronised with every other instance of that cycle. Spectrum is one of the nodal concepts making up the fundamental generic organisation concept which is the basic building block of all processes and functionality in the network.
The methods of spectrum are an interface between the local nodal cycle range and the environment specific integration with time. Each local cycle within spectrum exhibits a loop of which is hooked in to nodal reduction each time it activates, and hooked back in to the cycle again when all the recipients have been reduced.
