A method of processing a detection signal contaminated with noise is presented. The detection signal is a signal for detecting a substance ingested by a subject and has a signal profile formed of a peak and a decaying slope. The method includes the steps of: reading the detection signal, detecting noise in the detection signal; identifying if the detection signal is recoverable based on one or more characteristics of the noise in the signal profile; and applying a signal recovery algorithm to recover the detection signal.
