Model
Jurusan Teknik ElektroSemester Genap Tahun Ajaran 2014/2015
Make understanding complex systems easier (simplifies)
Can be used to design – make models of new systems so can refine them
Makes communication about systems easier (e.g. a picture can communicate a thousand words)
Why do we need models?
