摘要:Level-crossing sampling scheme is a non-uniform sampling way which can lead to lower power consumption. Unlike the classic digital signal processing, it is based on the nature of the signal changes rather than Shannon sampling theory. In this paper, a new non-uniform filtering method based on over-sampled FIR filter and look-up table was proposed to process the level-crossing samples. It is shown by the experiments that the computational complexity of the proposed one is lower than that of the uniform filtering and existing non-uniform FIR filtering techniques.
