关于科技利弊英语作文?

tools,suchascalculator,computer,etc,appear in our daily life。

we use themwherever and whenever we are,so that our life becomes easier and more comfortable than before. 

However,does anyone think about what problems science and technology have caused to happen in this world?To some degree,it's more serious than that we consider.We human indeed use them to improve our living standard,but on the other hand,we are becoming lazier,more reliable than we used to be.

All day long those hi-tech products accompany us,then we have either no space or time to think,as well,communication between each other decreases,and what takes place of it is the huge indifference and gap among human.

As we all know , the time of 5G technology is coming , it is called the fourth industrial revolution , future of computer science lies in the artificial intelligence,it is the research and artificial simulation of human thought and eventually be able to make a human like to think the same machine , for human services and to help people solve problems.

数字化的优缺点?

a.数字信号与模拟信号相比,前者是加工信号。加工信号对于有杂波和易产生失真的外部环境和电路条件来说,具有较好的稳定性。可以说,数字信号适用于易产生杂波和波形失真的录像机及远距离传送使用。数字信号传送具有稳定性好、可靠性高的优点。根据上述的优点,还不能断言数字信号是与杂波无关的信号。

数字信号本身与模拟信号相比,确实受外部杂波的影响较小,但是它对被变换成数字信号的模拟信号本身的杂波却无法识别。因此,将模拟信号变换成数字信号所使用的模/数(A/D)变换器是无法辨别图像信号和杂波的。

b.数字信号需要使用集成电路(IC)和大规模集成电路(ISI),而且计算机易于处理数字信号。数字信号还适用于数字特技和图像处理。

c.数字信号处理电路简单。它没有模拟电路里的各种调整,因而电路工作稳定、技术人员能够从日常的调整工作中解放出来。

例如,在模拟摄像机里,需要使用100个以上的可变电阻。在有些地方调整这些可变电阻的同时,还需要调整摄像机的摄像特性。各种调整彼此之间又相互有微妙的影响,需要反复进行调整,才能够使摄像机接近于完善的工作状态。在电视广播设备里,摄像机还算是较小的电子设备。如果摄像机100%的数字化,就可以不需要调整了。对厂家来说,降低了摄像机的成本费用。对电视台来说,不需要熟练的工程师,还缩短了节目制作时间。
