数字逻辑课后答案1-7章, 1. 什么是模拟信号?什么是数字信号?试举出实例。 解答 模拟信号-----指在时间上和数值上均作连续变化的信号。例如,温度、压力、交流电压等信号。 数字信号-----指信号的变化在时间上和数值上都是断续的,阶跃式的,或者说是离散的,这类信号有时又称为离散信号。例如,在数字系统中的脉冲信号、开关状态等。 2. 数字逻辑电路具有哪些主要特点?
Digital logic after the answer 1-7 1 What is an analog signal? What is a digital signal? Give examples.----- Represents an analog signal and the answer value for the average time on a continuously varying signal. For example, temperature, pressure, the AC voltage signal. Digital signal----- refers to a change in the signal and the time value is intermittent, step-like, or that is discrete, such signals are sometimes called discrete signals. For example, in a digital system of the pulse signal, the switch status. 2 What are the main digital logic circuits with features? (2013-12-04, PDF, 1247KB, 下载2次)

哈代是20世纪最优秀的数学思想家,同仁公认他是“真正的数学家是纯粹中最纯粹的”。这篇“自白”是他数学创造力衰退时写下的心酸文字。   在哈代的笔下,数学远远不仅是一门科学,还是艺术,是娱乐,是真善美。   本书刚出版,就被誉为堪与亨利·詹姆斯的笔记媲美的对“创造性艺术家的最佳描述”。   C·P·斯诺的长篇前言满含深情地回顾了哈代的一生,栩栩如生地讲述了他的学术生活和有趣的业余爱好。
Hardy in the 20th century' s best mathematical thinker, colleagues recognized him as " a true mathematician is purely the most pure." This " confession" is his mathematical creativity to write a sad word recession. In Thomas Hardy' s novels, mathematics goes far beyond a science, or art, entertainment, the most sublime. This book just published, praised as worthy of Henry James' s notes comparable to " the best description of the creative artist." C · P · Snow' s lengthy preamble laden with deep feeling reviewed Hardy' s life, vividly recounted his academic life and interesting hobby. (2009-10-15, PDF, 577KB, 下载13次)
