Abstract

Close-form representations for the permissible sampling rates on the first-order sampling of two-band bandpass signals are presented in this paper. It is shown that the new sampling rates are much lower than the Nyquist rate for signals with scattered passbands. A fast algorithm is developed for the symbolic operations on intervals, which makes the proposed sampling scheme more applicable.
