Abstract
A method may include receiving an input signal, generating a baseline signal based on the input signal, generating a corrected input signal by subtracting the baseline signal from the input signal, determining a threshold level change of the input signal when the corrected input signal exceeds a level change threshold, and responsive to the threshold level change, updating the baseline signal to the level change threshold.
