Conference Title: TENCON 2022 - 2022 IEEE Region 10 Conference (TENCON) Conference Start Date: 2022, Nov. 1 Conference End Date: 2022, Nov. 4 Conference Location: Hong Kong, Hong KongPhotoplethysmogram (PPG) signals are often assessed using the transmission and reflection techniques, which detect light passed through or reflected by tissue. The transmission technique is appropriate for body sites with thin tissue, such as the index finger. In contrast, the reflection approach applies to most body sites. As each body site impacts inducing noise while acquiring PPG, this study investigates the quality of PPG signal obtained from five body sites, i.e., fingertip, forehead, toe, wrist-upper, and wrist-lower. After denoising with the Savitzky Golay filter, we calculated popular state-of-the-art parameters to quantify the obtained denoised signal to indicate the quality of PPG. Simulation results after denoising and analysis reveal that the PPG acquired from fingertip exhibits the highest quality and yields a signal-to-noise ratio $SNR=39.8672dB$ with a minimum percentage root mean square difference $(PRD)$ of 1.0154 as compared to the PPG acquired from other body sites.
