Is PPG a periodic signal?

The PPG signal exhibits a quasi-periodic pattern consisting of an arterial pulse wave for each heartbeat.

What are signal processing techniques?

Signal processing techniques are used to optimize transmissions, digital storage efficiency, correcting distorted signals, subjective video quality and to also detect or pinpoint components of interest in a measured signal.
