Tests for voltage input thresholds can be used to make important distinctions about the characteristics of a device during validation, as well as the quality of a device during production test.
Process-oriented programming is a programming paradigm that separates the concerns of data structures and the concurrent processes that act upon them.
When changes are made to the main procedure (top), those changes can cascade to the sub procedures of main, and the sub-sub procedures and so on, where the change may impact all procedures in the pyramid. One alternative to procedural programming is object oriented programming. Object oriented programming is meant to address the difficulties with procedural programming. In object oriented programming, the main modules in a program are classes, rather than procedures. The object-oriented approach lets you create classes and objects that model real world objects.
