Abstract
A method for determining a threshold for spike detection in a noisy signal in real-time is provided. The method includes estimating a current variability of noise in the noisy signal according to a measured instantaneous value and a window of previous instantaneous values using a sigma-delta control loop, determining the threshold based on the estimated variability of the noise; and repeating the steps to update the estimate of the variability of the noise and adjust the threshold in real-time as the noisy signal changes. A non-transitory computer-readable storage medium for executing the method on a processing unit, and a low-power digital system implementing the method are also provided.
