33 Chapter 1 Introduction (引言) 1.1 About Digital Design(关于 “ 数字设计 ”) Another name “Logic Design”. The goal of design is to Build System. Digital Design is engineering, and engineering means “Problem Solving”. Only 5%-10% is the Creative part of Design. Much of the rest is just “Turning the Crank（曲 柄）”. Important Themes（主题） in Digital Design（P2) Digital Logic Design and Application (数字逻辑设计及应用)
Why Study Digital Design? Look“ under the hood(覆 盖)” of computers cde Solid understanding -- better Digital oircuits programmer when aware of inside hardware resource issues Satellites Video Musical Portable players recorders instruments musIc players Cell phones Cameras TVs ??? 1995 1997 1999 2001 2003 2005 2007 Years shown above indicate when digital version began to dominate 34-(Not the first year that a digital version appeared)
