Abstract: | The parity encoding of binary sequences, which is essentially the inverse operation to the differentiationof binary sequences, partitions the sequences into cycles of sequences. The spectrum of these cycles is shown tobe a fractal-like semi-infinite sequence of powers of 2, with the property that truncating it at the(n + 1)st term yields the cycle spectrum for the parity encoding of the n-bitbinary sequences. A simple and complete characterization of both the cycles and of the cycle spectrum isgiven. |
