Question

1.Representing Digital Information Electrically.In digital electronics,digital variables are represented by logic levels.At any given time,a voltage is expected to have one value or another,or more precisely to lie within one region or another.In a typical system,a voltage between 0 and 0.8V would be considered a digital zero,a voltage between 0.8~2V would be forbidden; that is if the voltage fell within this range,you would know that the digital equipment needs repair.These definitions are shown in Fig.4.1

2.The use of electrical motors has increased for home appliances and industrial and commercial applications for driving machines and sophisticated equipment.Many machines and automated industrial equipment now require precise contorl.This motor design and complexity has changed since early DC motors which were used primarily with railroad trains.Motor control methods have now become more critical to the efficient and effective operation of machines and equipment.Such innovations as servocontrol systems and industrial robots have led to new
developments in motor design.

Answer 1

1.表征电子数字信息。数字电子产品中，数字变量由逻辑电平来表示。在任一给定时间，期望的电压是某一个值，更准确地说是处于某个范围内。在一个典型系统中，电压在0至0.8V被认为是数字0，电压在0.8~2V之间被禁止；即如果电压处于0.8~2V，你就知道数字设备需要维修。上述定义如图4.1所示。
2.家电和工商业应用中越来越多地使用电机来驱动机器和精密设备。现在，许多机器和自动化工业设备都需要精确控制。这个电机设计和复杂程度自早期的直流电机以来已经有所改变，早期的直流电机主要用于火车上。现在，电机控制方法对于高效操控机器和设备极其重要。伺服控制系统和工业机器人等创新带来了电机设计的新发展。
