【摘要】 基于(+1,-1)的谱技术在数字逻辑中有许多应用.为了进一步补充谱技术理论,从归一化的Haar矩阵出发,通过对矩阵的性质分析,提出了(0,1)编码的归一化的Haar变换谱系数图——R谱系数图;提出了R谱系数图与K图的基于折叠加减的图形互换法,并举例说明了转换过程.应用表明,对5变量以下的函数该方法具有简单、直观和准确的特点.进一步完善了(0,1)编码的谱技术理论,有助于开拓谱技术在数字电路故障检测等方面的应用.更多还原

【Abstract】 There are a lot 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.更多还原
