Mapping of spectral coefficients for normalized Haar transform in (0,1) coding and the transformation between to K map

There are a tot of applications for spectral techniques based on coding （＋ 1, - 1）in digital logic. In order to complement the spectral technique theory, by analyzing the features of Haar matrix, graphic transformation methods between spectral coefficient R map and K map were presented. Several examples were also given. It showed that the graphic methods based on folded addition and subtraction have several advantages such as intuition, simplicity, and precision. The discussion may of certain significance to improve the spectral technique theory and be helpful to expand the application area for spectral techniques.
