Graphic transformation between spectral coefficient map and K-map based on coding of 0-1

To complement the spectral coefficient theory and apply spectral technology to detecting digital circuit faults, the spectral coefficient map based on the coding of(0,1) space is proposed. By analyzing the features of Hadamard matrix, the paper presents three graphic transformation methods between spectral coefficient map and K-map: graphic transformation method based on line-vector groups, graphic transformation method based on non-zero terms and graphic transformation method based on folded addition and subtraction, and gives some practical examples for each method. Furthermore, the application area for these transformation methods is discussed in the paper. For the function of six variables or less, these methods have the feature of simplicity, intuition and precision.
