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?
