Abstract

Apparatus and method for use with a cathode ray oscilloscope for displaying from any desired perspective a multi-dimensional surface evolving in time multi electrical signal are introduced to attachment to related electrical signal-carrying means, a multiplicity of two-dimensional rotators. For the number N of signals and therefore of N dimensions there are EQU N!/2 (N-2)! two dimensional rotators. Each rotator is connected to a different pair of these signals and provide two-dimensional rotation of the paired signals. The rotators are connected together to produce signal outputs corresponding to the number of signals introduced, each signal passing through two rotators as each signal makes its way to its respective signal output. The outputs are connected to a cathode ray oscilloscope, at least two at a time.
