.　　5．对每个例子进行了仔细检查，确保有简洁的解释、足够的中间步骤以及合适的图。与第六版类似，对于每个例子都以测试题的方式措辞，以辅助解题，但并不解释概念。
　　6．根据许多学生的建议，增加了大量章后习题，包括直观的“树立信心”的习题。
　　7．每章开始时给出重要概念，以便给出该章内容的快速参考。
　　8．增加了一些新的实际应用章节，并且更新了现有内容。
　　9．增加了一些新的四色照片，以增加可视效果。
　　10．本书附带了新的多媒体软件，包括期待已久的对COSMOS习题库解答系统的更新。
　　Bill Hayt先生在本书第六版修订工作刚开始时就去世了，这一消息对我来说是始料未及的重大打击。我一直没有机会与他探讨本书的修改事宜。我希望本书的修订有助于其面向新一代聪明的年轻工科学生，同时我们(durbin@ieee．org和McGraw-Hill的编辑们)都欢迎学生和教师提出意见和反馈，无论是正面的还是负面的，我们都非常感谢。
　　本书的完成是团队的工作成果，许多人参与其中，还有许多人提供了帮助。非常感谢McGraw-Hill的编辑和工作人员长期以来的支持，其中包括Melinda Bilecki，Michelle Flomenhoft，Kalah Cavanaugh，Michael Hackett，Christina Nelson，EricWeber，Phil Meek和Kay Brimeyer。还要感谢我们当地的McGraw-Hill院校代表Nazier Hassan，他来我们学校拜访时非常关心本书的进展。与他们一起工作是一件美好的事情。...
