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?
