伯努利装错信封问题-综合[难]
题目描述
    某人写了n封信，同时为每一封信写1个信封，共n个信封。如果把所有的信都装错了信封，问共有多少种？（这是组合数学中有名的错位问题。著名数学家伯努利(Bernoulli)曾最先考虑此题。后来，欧拉对此题产生了兴趣，称此题是“组合理论的一个妙题”，独立地解出了此题 ...

A digital filter structure for wideband filtering
is proposed. It consists of two allpass filters and a linearphase
FIR filter. One major advantage of this structure is
that the allpass filters are functions of zM which implies
that the maximal sample frequency is M times higher ...
