请高手帮我翻译 这段文字 拜谢！

采用高速度8位AVR单片机和FPGA可编程数字芯片设计转速表正弦波信号发生器，取代对应传感器，信号发生器是为汽车车速表生产过程中的校准、老化而设计的仪器。采用直接数字合成技术产生正弦波信号，用高速现场可编程门阵列(FPGA)实现直接数字合成技术，因此信号源具有高精度高可靠性的特点，将DDS技术融入测试系统，实现用正弦波信号发生器取代速度传感器，同时作为通用信号发生器的校准设备，设计结果表明系统可满足复杂测试环境的要求并且具有一定扩展性。

Answer 1

After a macro processor of 8 of AVR of the high speed is adopted, a tip and the rotating speed of the number FPGA programs are designed and the signal generation capacity of the signature wave is expressed.A signal generator replaces and answers to a sensor, and it's apparatus with a design in correction in the production process of the speedometer and aging storage of a car.Of the door which adopts synthetic technology of a direct number, produces a signal of a signature wave and programs a high-speed site, a degree, after (FPGA) is lined up and synthetic technology of a direct number is achieved.Therefore with the feature of the highly precise reliability by which a signal source has, DDS technology, after realization dissolves and tests a system, and replaces a sensor of the speed by the signal generation capacity of the signature wave.Equipment is corrected as the one of the signal generator in common use at the same time, and I'm expressing that the result of the design is able to satisfy that a system tests the one of the environment, finds the fixed scalability and lasts complicatedly.

Answer 2

Using high-speed 8-bit AVR Microcontroller and FPGA programmable digital chip design tachometer sine wave signal generator, replace the corresponding sensors, signal generator for the vehicle speed to form the production process of calibration, design and aging equipment. Direct digital synthesis techniques to generate sine wave signal using high-speed field programmable gate array (FPGA) for direct digital synthesis technology, Therefore signal source with high precision and high reliability features will DDS technology into the test system achieve sine wave signal generator used to replace speed sensors, as well as a general signal generator calibration equipment, The results show that the system designed to meet the complex requirements of the test environment and with a certain extension.
