摘要
ased on the 4-valued logic function in orthogonal area, a new series──the orthogonal 4-valued function series──is proposed. Having good performances, the new series is superior to Walsh function and block pulse function in the computation of truncation errors.
利用正交域的四值逻辑函数，提出一种新的级数：正交四值函数级数。这种级数具有优良的性能，在截断误差的计算上优于沃尔什函数和方块脉冲函数。
