This means that the total system performance requirements must be defined and that the allowable signal degradation must be allocated among signal acquisition, headend processing, distribution system, and terminal equipment.

In this chapter, quality standards and the question of allocation are discussed. Next, the calculation of the cascaded broadband network sections are addressed. Finally, the typical performance of a modern HFC distribution system is analyzed, including ...
