代码说明:

设f(x)=1+x+x2+x5+x27,试分别写出实现下列移位寄存器的程序: 以f(x)为联接多项式的DSR; 以f(x)为联接多项式的LFSR。 可供选择的联接多项式: f1(x)=1+x+x4+x6+x30; f2(x)=1+ x3+ x31; f3(x)=1+ x6+ x31; f4(x)=1+ x7+ x31; f5(x)=1+ x13+ x31; -Let f (x) = 1 x x2 x5 x27, respectively try to write the following Shift Register : f (x) connected to the DSR polynomial; f (x) for connectivity polynomial LFSR. Connection options polynomial : f (x) = 1 x x4 x6 x30; F2 (x) = 1 x3 x31; f3 (x) = 1 x6 x31; f4 (x) = 1 x11 x31; f5 (x) = 1 x13 x31;

  • EAQUAL 1.03
     What is EAQUAL?     The intention of EAQUAL is to provide a objective quality measure for coded/ decoded audio      files. Currently the code is based on the ITU-R recommendation BS.1387.      EAQUAL will not supersede listening tests, but can be a useful tool to support listening tests,      categorize different coding algorithms and find bugs in algorithms. The more input files are      taken for the analysis, the better the results of EAQUAL will fit the reality.
