1.Based on the lifting scheme wavelet transform firstdiscovered by Sweldens in 1996, a efficient VLSI architecture ofJPEG2000 CDF (2,2) integer- to- integer discrete wavelet trans-form is presented, and the range of CDF (2,2) wavelet coeffi-cients is analyzed.
根据1996年Sweldens等人提出的提升小波变换方法,设计了一种有效的JPEG2000CDF(2,2)整数小波变换的VL-SI实现结构,并对小波系数的变化范围进行了分析。收藏指正
2.The new device is suitable for discrete or monolithic applications. A second order high—pass filter, as an application example, is built using two fabricated OTAs and discrete capacitors, and the filter has a broad cut—off frequency, fo, adjustable range from 10 KHz to 300 KHz.
作为一个应用实例,用两个电流提升OTA及两个分立电容组成了二阶高通滤波器,该滤波器的截止频率f_O可由电信号连续调节,其可调范围是从10KHz至300KHz。收藏指正
3.According to the materials of inbore or out of bore mal-functions of guns,this paper deals with fundamental models of safety failures of projectile-fuze systems,A set of discrete and finite element modal analysis methods have been put forward,which verified by modal experiments and range testings.
该文根据火炮膛炸、早炸事故资料,提出了安全失效的基本模式,建立了一套应用离散模型和有限元模型进行理论分析,用模态试验和靶场试验进行验证的方法。收藏指正
4.In photomechanical reproduction, a line screen breaks the wide tonal range found in the original into discrete intervals from 1% to 99%), creating a halftone dot pattern.
中义在制版照相的复制过程中,用线状的平网将原稿的浓度?围分解为1%到99%的不连续区段,并产生半色调的网点花纹。半色调的网点值是以百分比(%)来描述。收藏指正
