| Abstract: | A strategy for the equivalent nonuniform time sampling of periodic signals is proposed. It is easier for the hardware implementation because the nonuniformly sampled data are procured by means of uniform sampling methods. The interpolation formula for the nonuniformly sampled data is derived. The strategy has many advantages when compared with uniform sampling method in the reconstruction of signals and the harmonic analysis of signals. |
