This step is performed by a sample and hold circuit, which samples at regular intervals called . The length of the sampling interval is the same as the sampling period , and the reciprocal of the is the sampling frequency f s. According to the Nyquist theorem, a signal with a maximum frequency of W Hz (called a band-limited signal) must be at least 2W samples per second to ensure accurate recording. When this minimum is not respected, called aliasing occurs.R ①sampling intervals ②distortion ③conversion ④sampling period ⑤sampled四、Comprehension. choose the best answer according to this passage.Previously in this chapter, we’ve discussed how data elements (characters, fields, and records) c an be organized in files. In file-oriented systems, each file is independent and contains all the information necessary to process the records in that file. In a database, the data is organized in multiple related files. Because these files are related, us er can access data in multiple files at one time. A database management system (DBMS) is the software that allows the user to create, maintain, and report the data and file relationships. By contrast, a file management system is software that allows the user to create, maintain, and access one file at a time.There are problems with traditional data management. Many result from viewing applications independently. For example, consider payroll. Most organizations prepare their payrolls by computer because using a machine instead of a small army of clerks saves money. Thus, the firm develops a payroll program to process a payroll file. Inventory, accounts receivable, accounts payable, and general ledger analysis are similar applications, so the firm develops program, and inventory file, an accounts receivable program, an accounts receivable file, and so on. Each program is independent, and each processes its own independent data file.The solution to these problems is often organizing the data as a single, integrated database.How does the use of a centralized database solve the data redundancy problem? All data are collected and stored in a single place; consequently, there is one and only one copy of any given data element. When the value of an element (an address, for example) changes, the single database copy is corrected. Any program requiring access to this data element gets the same value, because there is only one value.1.In file-oriented systems, each file is independent and contains all the information necessary to processthe in that file.A. elementsB. recordsC. dataD. software2.

Think of it simply as a tool. One that uses light instead of mechanical energy. And a tool that allows its user to control the form and amount of energy directed at a particular place. The laser can cut through a two-inch-thick sheet of steel or detect a single atom. It can perform a task as dramatic as igniting a thermonuclear fusion reaction or as seemingly mundane as drilling a hole in a baby-bottle nipple.A laser is a device that produces a very special kind of light. Y ou can think of it as a super flashlight. But the beam that comes out of a laser differs from the light that comes out of a flashlight in four basic ways: Laser light is intense. Y et only a few lasers are powerful. That’s not the contradiction you might think.. Intensity is a measure of power per unit area, and even a laser that emits only a few milli-watts can produce a lot of intensity in a beam that’s only a millimeter in diameter.Laser beams are narrow and will not spread out like ordinary light beams. This quality is called directionality.Laser light is coherent. This means that all the light waves coming out of a laser are lined up with each other.Lasers produce light of only one color. Or, to say it in a more technical way, the light is monochromatic. Ordinary light combines all the colors of visible light (i.e., the spectrum). Mixed together, they come out white. Laser beams have been produced in every color of the rainbow (red is the most common laser color), as well as in many kinds of invisible light, but each laser can emit one color and one color only.1. The laser can cut through a two-inch-thick sheet of steel or detect a single atom.（）2. The flashlight can perform a task as seemingly mundane as drilling a hole in a baby-bottle nipple.（）3. All the light waves coming out of a flashlight are lined up with each other.（）4. Laser beams are narrow and will not spread out like ordinary light beams.（）5. Ordinary light combines all the colors of visible light . （）六、T ranslate the following sentences into Chinese.1.The low pass filter, called the anti-aliasing filter, removes all frequencies above half the selected sampling rate.2. The A/D converter chooses a quantization level for each analog sample. An N-bit converter chooses among 2N possible quantization levels. The larger the number of levels, the smaller the quantization errors, calculated as the difference between the quantized level and the true sample level.3. Once digital signal processing is complete, digital-to-analog (D/A) conversion must occur. This process begins by converting each digital code into an analog voltage that is proportional in size to the number represented by the code.4. For example, signals whose frequencies are restricted to a narrow band of high frequencies can be sampled ata rate similar to twice the width of the band instead of twice the maximum frequency.5. The images of each frequency f present in a sampled signal appear, through sampling, at the infinite number of frequencies kf s±f Hz.6. After a brief acquisition time, during which a sample is acquired, the sample and hold circuit holds the sample steady for the remainder of the sampling interval. This hold time is needed to allow time for an A/D converter to generate a digital code that best corresponds to the analog sample.答案一、1. spectrum 2. laser beam 3. thermonuclear4.digital-to-analog (D/A) conversion5. database6. extraterrestrialImpediment 8. compatibility 9.
