On estimation of multiple frequencies in undersampled complex valued waveforms

In this correspondence, the determination of multiple frequencies in undersampled waveforms is studied using multiple smaller size discrete Fourier transforms (DFT). Given the sizes of multiple DFT, a range for the detectable frequencies in undersampled waveforms is presented.
