摘 要：針對(duì)目前小波分析儀功能簡單、集成性和便攜性差以及處理復(fù)雜信號(hào)速度慢等缺點(diǎn)，設(shè)計(jì)基于DSP技術(shù)一體化框架波分析儀。該分析儀是在國內(nèi)外最新的小波分析理論研究成果的基礎(chǔ)上，結(jié)合虛擬儀器技術(shù)、一體化儀器技術(shù)和數(shù)字信號(hào)處理（DSP）技術(shù)設(shè)計(jì)開發(fā)的，其既能實(shí)現(xiàn)傳統(tǒng)的小波分析，還能實(shí)現(xiàn)新型非平穩(wěn)信號(hào)分析方法——框架波變換。該一體化框架波分析儀不僅功能強(qiáng)大，而且通過引入DSP技術(shù)大大提高了信號(hào)處理的速度，適合于非線性非平穩(wěn)信號(hào)的動(dòng)態(tài)實(shí)時(shí)分析。

Abstract: 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 has powerful abilities for signal analysis and can improve the speed of dealing with the signal， therefore it is very suitable for analyzing nonlinear and non-stationary signals in real-time.
Key words: frameset； DSP technology； integrated instrument technology； virtual instrument
