Fig. 1

This figure illustrates the stages of processing PPG signals. The plot shows a 16-minute segment of the signal centered around the measurement point (tm), including 8 minutes before and after. It also displays the filtered signal, demonstrating the removal of noise and artifacts using the described methods in Refining signals with advanced filtering techniques.
