Abstract
Methods, computer-readable mediums, and a circuit are provided. In one embodiment, a method is provided which obtains a digital sample. The method calculates a second derivative of the digital sample and thereafter determines when the second derivative passed through a zero crossing point. A master clock value and the second derivative value before and after the second derivate passes through zero are used to calculate a clock fraction and add the clock fraction to the master clock value. Thereafter, an event start signal is triggered to initiates signal processing.
