Exterior system analysis — Defining input/output parameters for system design

An important step in any system definition is exterior design. Exterior design consists primarily of identifying and characterizing the noise and bandwidth parameters of the input/output signals which exist in both continuous and discrete, and random and deterministic forms. The multiple inputs and outputs may be related through a matrix model for analyzing system weighting factors and system errors. The weighting factors determine interior system design. A review of system input/output attributes is presented to aid in the identification process of exterior system design. Probability analysis is proposed as the unifying criterion to balance system design trade-offs.
