Classifying 3-band cardinal orthogonal scaling function
Guochang Wu, Zhengxing Cheng · 2009
The 3-band cardinal orthogonal scaling function with compact support is of interest in several applications such as sampling theory, signal processing, computer graphics. In this paper, We generalize some results of the cardinal orthogonal scaling function from the 2-band case to the 3-band case. We give the characterization. Also,we give some examples to prove our theory.
