Overview Vector space Unused Vectors Used Vectors Inputs have to be meaningful for better coverage. While using random vectors it is impossible to visit the whole vector space. Spectral coefficients give us links from one vector space to another space which could have vectors within close range that will be able to give better fault coverage. Spectral analysis helps concentrate only on the vectors that are relevant thus reduces the white noise . Most importantly sequential circuit tests are not random so this method helps as this co-relates the vectors to one another.
