Abstract
An electronic fitness device comprises a first optical transmitter, a second optical transmitter, a first optical receiver, a second optical receiver, and a processing element. The first optical transmitter is configured to transmit a first optical signal having a first wavelength and the second optical transmitter is configured to transmit a second optical signal having the first wavelength. The first and second optical receivers are configured to receive the first and second optical signals, respectively, and to generate first and second photoplethysmogram (PPG) signals, respectively, resulting from the received optical signals. The processing element is configured to receive and compare the first and second PPG signals, identify a common component present in the first and the second PPG signals based on the comparison, and generate a cardiac component from the first and second PPG signals based on the identified common component.
