SHA-1(Secure Hash Algorithm)是美国国家标准局(National Institute of Standard and Technology NIST)为了配合数位签章演算法(Digital Signature Algorithm DSA)的使用所发布的联邦资讯处理标准-FIPS PUB 180-1(Federal Information Processing Standard Publication 180-1),而SHA-1 则是SHA-1 (FIPS180)的改良版,现今与MD5 皆广被使用拿来做密码验证功能.其设计的方法是根据MD4,来对输入的资料讯息(Message)产生出一个160 位元的讯息摘要(Digest) ,对於资料安全性提供了有效的保障.

This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmitter. The fractional-N synthesizer forming the basis of the transmitter uses a combined phasefrequency detector (PFD) and digital-to-analog converter (DAC) circuit element to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.

The neuro-fuzzy software for identification and data analysis has been implemented in the MATLAB language ver. 4.2. The software trains a fuzzy architecture, inspired to Takagi-Sugeno approach, on the basis of a training set of N (single) output-(multi) input samples. The returned model has the form 1) if input1 is A11 and input 2 is A12 then output =f1(input1,input2) 2) if input1 is A21 and input 2 is A22 then output =f2(input1,input2) 看不懂，据高手说，非常有用。
