谁能帮我翻译一下？？用英文翻译，我论文里面要用。谢谢各位了！

模拟信号的数字化过程需要经过三个步骤即抽样、量化与编码。抽样是指在时间上将模拟信号离散，用每隔一定时间的信号样值序列来代替原来在时间上连续的信号。量化是指用有限个幅度值与原来连续变化的幅度值相似，把模拟信号的连续幅度变为有一定限量的、间隔的离散值。编码就是按一定的规律，把量化后的值用二进制数字来表示，再转变为信号流。这样得到的信号就可以通过卫星通道、电缆等数字线路进行传输，在接收处与上面的模拟信号数字化过程相反，经过滤波还原为原来的模拟信号。这种数字化过程也叫做脉冲编码调制。模拟信号的数字化过程如图二所示。输出信号模拟信号消息的运载是通过信号实现的，所以说信号是消息的载体。随着科技的迅速发展，二十一世纪步入了信息时代，信息传输无处不在，信息技术的发展和运用为教学提供了丰富的学习资源。我们有必要了解信息传输常用的两种模式，即模拟信号与数字信号。在传统的通信中，线路中传送的电信号是跟随声音大小的变化而变化的，由此发出的电信号是连续的，它的原理是把信息转化成与它一模一样的电信号，传输出去，再由接收电信号的接收设备还原信息信号。

The analog signal digital process takes three steps: sampling, quantization and coding. Sampling is analog signal discrete in time, with certain interval, signal sample sequence in time to replace the original continuous signal. Quantization is similar to the original continuous variation of amplitude with finite amplitude, the amplitude of an analog signal into discrete have certain limit, interval value. Code is according to certain rules, the quantized values are represented by binary numbers, and then into a signal flow. Signal thus obtained can be transmitted through the satellite channel, cable digital line, in the reception and the analog signal digital process on the contrary, after filtering to restore the original analog signal. This process is called digital pulse code modulation. The process of digital analog signal as shown in figure two. Carrier output signal message is through the signal, so that the signal is the information carrier. With the rapid development of science and technology, in twenty-first Century entered the information age, information transmission is everywhere, the development of information technology and application provides rich learning resources for teaching. It is necessary to understand the information transmission two kinds of mode is used, namely the analog signal and digital signal. In the traditional communication, electrical signal transmission line is to follow changes in size of the sound changes, telecommunication, this issue is continuous, it is the principle of the information into electrical signals, and it is as like as two peas transmission out, again by the receiving device receives the electrical signal is the original information signal.

Answer 2

Analog signal digital process takes three steps as sampling, quantization and coding. Sampling refers to the analog signal is discrete in time, with every certain time sequence signal sample value instead of the original continuous signal in time. Quantitative refers to the use of finite amplitude value and range value of the original continuous change are similar, the analog signal to have certain limit, the margin of continuous interval discrete values. After code is according to certain rule, the quantitative values in binary numerals, again into signal flow. The resulting signals can be transmitted through satellite channels, cable digital circuit, the receiving place, in contrast to the analog signal digital process of the above, revert to the original analog signal after filtering. The digitization process is called pulse code modulation. The analog signal digital process as shown in figure 2. The output signal to analog signal message delivery are implemented through the signal, so the signal is the carrier of the message. With the rapid development of science and technology, the 21st century into the information age, information transmission is everywhere, the development of information technology and apply for the teaching provides a rich learning resources. We commonly used it is necessary to understand the information transmission of two kinds of modes, namely analog signals and digital signals. In traditional communication, transmit electrical signals is in line with the size of the voice changes, thus the electric signal is continuous, its principle is to put the information into an identical electrical signal, transfer out, again by the signal receiving device reduction information receiving electrical signals.

Answer 3

The digitization process of analog signals via three steps, i.e. sampling, quantization and encoding. Sampling refers to the analog signal of the time will discrete sequence of signal samples with every predetermined time instead of the original signal is continuous in time. Quantization means with a finite number of amplitude values similar to the original amplitude value changes continuously, the continuous analog signal amplitude becomes a certain limit, spaced discrete values. Coding according to certain rules, to quantify the value of binary digits to represent, and then into the signal flow. The signal thus obtained can be transmitted via the satellite channel, cable and other digital line, the analog signal is digitized at reception above process is reversed, after filtering restored to the original analog signal. The digitization process is also called pulse code modulation. The digitization process of the analog signal is shown in figure II. The message carrying the analog signal of the output signal is achieved through the signal, so that the signal is a carrier of the message. With the rapid development of science and technology, the 21st century has entered the information age, information transfer everywhere, and the development and use of information technology to provide a wealth of learning resources for teaching. We need to understand the two modes of information transmission, the analog signal and digital signal. In the traditional communications, an electrical signal transmitted in the line is to follow changes in the size of the sound changes, whereby the electrical signal issued is continuous, its principle is the information into electric signal identical with it, the transmission out then by the receiving apparatus to receive the electrical signal to restore the information signal.
