Opis

This text emphasizes the concepts and applications of modelling and design. It discusses modern techniques such as CAD tools and implementation via digital control. Numerous design examples place the theory in context.

Recenzje

"It is a very good tutorial guide and explains some basic concepts in a commendably clear manner...students will find it a useful aid, and it is recommended as such."
-Measurement and Control

"Bissell provides good classical value for money."
