Abstract
Methods and systems for decimating a waveform are disclosed. The method includes dividing the waveform into a plurality of sections and performing a second order derivative operation on the sections and determining corresponding derivative values. The method further includes classifying the section as a linear region if the derivative value is within a threshold range and classifying the section as a non-linear region if the derivative value is outside the threshold range. The method also includes decimating data points of the linear regions using a coarse decimation to generate coarsely decimated data points and decimating data points of the non-linear regions using a fine decimation to generate finely decimated data points. The method also includes reconstructing a waveform using the coarsely and finely decimated data points.
