The design is a portable distortion degree tester, based on Field-Progranmmble Gate Array （FleA, EP2C20） as the cote, using harmonic analysis method which better solve the distortion problem of acctwacy. It can achieve the signal transformation from the time-domain to the frequency-donkain, and is widely used for signal spectrum analysis. All the componets used in the design are low power, high perf-, low drift and industrial grade compionents. The reference voltage sources of ADC and DAC have identical performance of high stability, high precision. The dtr.k is the precise stable clock with FPGA temperature compensation. This project can get the cost-effective, high-precision, low power and portable design goals.展开更多

Art design is the biggest characteristic of individual creativity, art need to createinstead of imitating and copying. In the process of production, creative thinking is the key to a successful art products, grasp the technology canproduce the same design and the product, but the hand of art and technology perfect combination is possible to create the art products. For designand production activities in the basic technical indexes and basic operation can understand and grasp the designer is unable to turn the designinto product, higher vocational art and design. This paper integrates the state-of-the-art angles and perspectives on the issues that hold specialmeaning.展开更多
