A system and method for PPG signal quality assessment is provided. The method includes obtaining a PPG signal captured using a testing device in real-time. The PPG signal is segmented into a first plurality of PPG signal samples such that length of each of the first plurality of PPG signal samples more than a threshold length. A signal sufficiency check (SSC) is performed for each first PPG signal sample of the first plurality of PPG signal samples to obtain at least a first set of PPG signal samples complying with the SSC. A set of features is extracted from the first set of PPG signal samples. Based on the set of features, each of the set of PPG signal samples is identified as one of a noisy signal sample and a clean signal sample using a plurality of Random Forest (RF) models created during the training phase.
