模拟试题一答案一、 Decide whether each of the following statements is true ()or false ()(20 points)1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 二、 Translate the following words and phrases into English (20points)1、 Inductor2、 square waves3、 the band-rejection filter4、 discharge5、 insulation resistance（2） Translate the following paragraph into Chinese(20points)二进制系统是计算机的基本语言。八进制和十六进制系统通常在计算机通信和计算机储存信息时用。计算机只能处理二进制系统或其它系统如八进制和十六进制中的二进制编码，所以十进制系统必须先转换成这些数字系统才能有计算机处理。当计算机对所给的信息处理完毕后，输出的信息是以非十进制的形式打印或显示出来。所以这些输出信息必须再转换成为十进制系统。（3） Answer the following questions with English (40points)1. Electronics is a part of the larger field of electricity. The basic principles of electricity are also common to electronics. Modern advances in the field of computer, control system, communications have a close relationship with electronics. The field of electronics includes the electron tube, transistor, integrated circuit and so on2、Eight types3、The integrated circuit is sometimes called an IC. An integrated circuit is a small electronic device made out of a semiconductor material. The first integrated circuit was developed in the 1950s by Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor.At todays level of development, it might comprise more than ten thousand separate electronic elements including elements of many functions, such as diodes, transistors, capacitors and resistors.模拟试题二答案a) Decide whether each of the following statements is true ()or false ()(20 points)1. 2. 3. 4. 5. 6. 7. 8. 9. 10、二、Translate the following words and phrases into English (20points)1. a bridge(full-wave) rectifier. 2. linear device3. timing simulation4. Alternating current circuits5. the combinatory logic electric circuit,三、Translate the following paragraphs into Chinese(40points)一个同步的计数器内部电路结构比较复杂，以保证所有的计数器输出都在每一个时钟脉冲输入时同时改变，同步的计数器可以避免异步计数器中可能出现的误计数。图7。6所示为同步计数器，所有的时钟输入端（CLK）是连接在一起的，进位输出信号CO接在下一个计数器的进位输入信号CI上，第一个计数器的CI应接在高电平（无进位信号）。 源程序中的每一条指令都与一条汇编语言语句一一对应。语句必须指明执行什么操作和对什么数据进行操作。因此，一条指令可以分成两个部分；操作码和操作数。操作码是指出要执行的操作，如典型的操作是加、减和移动。a) Answer the following questions (20points)1、 Give two input variables A and B, and an output variable Y. The expression Y=A or B means Y=1 if A=1 or B=1 or both A=1 and B=12.They are on-chip Memory, External Code Memory and External RAM模拟试题三答案一、 Decide whether each of the following statements is true ()or false ()(20 points)1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 二、 Translate the following words and phrases into English (20points)1. Plasma display 2. Semiconductor diodes3. polarized light.4. synthesis,5. types of filter 三、 Translate the following paragraph into Chinese(20points)AHDL是ALTERA硬件描述语言。它是一种高水平的硬件描语言。它运用布尔运算、算子、真值表和条件语言描述等。值得一提的是，它特别适合大且复杂的机械。在文本编辑器中我们使用AHDL模板。在基于AHDL的MAX+plus II中我们能学到关于AHDL语言的相关知识。.四、Answer the following questions (40points)1. Resistance is the opposition to the flow of current and is represented by the letter symbol R. The unit of resistance is the Ohm, expressed by using 2.The frequency of a waveform can be determined by counting the number of centimeters, horizontally, in one cycle of the waveform and the multiplying it by the setting time/cm control. For example, if the waveform is 2cm long and the control is set at 1ms/cm, the period would be 2ms. The frequency can now be found from the formula: f=1/T=1/2ms=500Hz.3. I think microwaves radiation cant be leaked Because its virtually impossible to be in contact with microwaves emitted from a microwave oven. There is some sort of pattered mesh covering on the doors of all microwaves. Because the waves are wider than the holes, the shield which is made of metal blocks the waves form going through the plastic door模拟试题四答案一、 Decide whether each of the following statements is true ()or false ()(40 points)1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 二、 Translate the following words and phrases into Chinese(20 points)1. 相关性和功率谱密度2. 场效应管三极管3. 两对偏转板4. 专供制造厂编程单元.5. 可编程逻辑控制器三、 Translate the following paragraphs into Chinese(20points)DSP 系统具有实时运算的特征，并注重高吞吐率和大量的算术运算。最显著的运算是乘法、加法或乘-累加。这些运算导致了新一代处理器的开发。它的结构和指令集根据DSP 运算要求编制。四、 Answer the following questions (20points)1、Richard E.Morley invented the PLC in 1968. After his invention, Morley founded the Modicon Corportation to produce and sell the concept of the PLC to industry. Before that time manufactures like GM or Ford would use electro-mechanical relays hooked to limit switches, push buttons, timers, counters and coils all interconnected to perform the “sequence of operation” needed to produce their Chevy or Lincoln. There were thousands of electrical connections involved. To understand this sequence and help in trouble shooting, Ladder Logic Schematics were used.Ladder Logic helped in understanding the “sequence of operation”, but thousands of hours would be required to make changes in the sequence to produce next years car model. The PLC concept of manufacturing put a stop to all this requiring from one model year to the next. The assemb
