Digital Devices
Gates（门电路）：
• 数字设计是工程，工程意味着解决问题
• Only 5%-10% is the Creative part of Design. Much of the rest is just “Turning the Crank”.
• 只有5%~10%是设计的创新部分，剩下的只是实现构想而已
Important Themes
• Good tools do not guarantee good design, but they help a lot by taking the pain out of doing things right.
• 好的工具并不能保证好的设计，但它能在正确完成设计工作时大大减轻你的 劳动。
• Digital circuits have analog characteristics. Know when to and when not to worry about the analog aspects.
• 数字电路具有模拟特性。要知道何时应该何时不应该考虑模拟特性。
• Document your designs, use consistent coding, organizational and documentation styles to make them understandable to yourself and to others.
Attenuation 衰减
Amplification 放大
模拟信号在传输过程中失真 数字信号仍然可以保持 0、1
Analog versus Digital
• Digital Circuits over Analog Ones
数字系统及其优越性
– Reproducibility of Results
结果再现性（稳定可靠、精度更高）
– Ease of design, Flexibility, and Functionality
易于设计，灵活性和功能性
– Programmability
可编程性（具有“智能”）
– Speed, Economy, and Steadily Advancing Technology
Analyse, Design, Test
• Analyse logic relationship between input & output Boolean algebra
