Abstract :
Cyclic and dyadic shifts of a periodic sequence are illustrated on the H diagram. Fast Walsh-Hadamard transform of the shifted (both cyclic and dyadic) sequence is represented graphically on the H diagram. The shift-invariant properties of the power spectrum are derived from these operations.
