摘　　要：针对目前小波分析仪功能简单、集成性和便携性差以及处理复杂信号速度慢等缺点,设计基于DSP技术一体化框架波分析仪。该分析仪是在国内外最新的小波分析理论研究成果的基础上,结合虚拟仪器技术、一体化仪器技术和数字信号处理(DSP)技术设计开发的,其既能实现传统的小波分析,还能实现新型非平稳信号分析方法——框架波变换。该一体化框架波分析仪不仅功能强大,而且通过引入DSP技术大大提高了信号处理的速度,适合于非线性非平稳信号的动态实时分析。Since the commonly used wavelet analyzers are not satisfactory for their simple functions, bad integration and portability with a low speed of dealing with complex signal, an integrated frameset analyzer was designed based on DSP technology. Based on the newest theoretical achievements on wavelet all over the world, this integrated frameset analyzer was designed and developed with virtual instrument technology, integrated instrument technology and DSP technology. This instrument can realize the functions of the traditional wavelet analysis and the new approach on analyzing nonlinear and non-stationary signals which is called frameset transform. This analyzer dealing signals with the signal, in real-time. has powerful abilities for signal analysis and can improve the speed of therefore it is very suitable for analyzing nonlinear and non-stationary signals in real-time.
