Abstract
A method and apparatus that provides a digital approximation of an input analog continuous-time signal using piece-wise linear waveform from key sampling points selected by a dynamic predictive sampling method. The apparatus includes a processing system or block to generate a dynamic prediction of the input signal as well as an upper threshold and a lower threshold to form a tracking window, a comparator that compares the input signal with the upper threshold and the lower threshold to determine if the prediction is successful, a counter to record timestamps between the unsuccessful predictions which are the selected key sampling points, and a processing block controlling predictions and sampling states of the system. The processing of the sampling points can include a neighbor amplitude filter and a slope filter.
