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.
Claims14
A method comprising:
- 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;
- generating an output flag indicative of the threshold level change;
- and
- outputting the generated output flag.
