Analysis of skewing in amplitude distributions of filtered m sequences

The skewing that is found to occur in the amplitude distributions of m sequences subjected to lowpass filtering is discussed. An analysis is presented which establishes a systematic relationship between the extent of skewing and the characteristic polynomial. The results show that the extent of skewing varies considerably for different m sequences of the same length. It is shown howthe skewing can be minimised by the choice of a sequence having an appropriate characteristic polynomial.
