다중 저속 ADC를 이용한 광대역 DFD 구조 설계.

This paper proposes an alternative method for measuring the frequency of a short-time signal in a wideband frequency range. A frequency measuring architecture comprising multiple sub-Nyquist sampling channels and a frequency estimator is proposed. The simulation results show that the proposed method has better frequency accuracy, though it uses lower sampling rates than typical DFDs for wideband input frequency range. [ABSTRACT FROM AUTHOR]
