Cyclic and Dyadic Shifts, Walsh-Hadamard Transform, and the H Diagram
December 1974 (vol. 23 no. 12)
pp. 1303-1306
K. Revuluri, Department of Electrical Engineering, University of Texas
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.
Index Terms:
Cyclic and dyadic shifts, fast Walsh-Hadamard transform, H diagram, power spectrum.
