Abstract
An electronic fitness device comprises a first optical transmitter, an optical receiver, and a processing element. The first optical transmitter is configured to transmit a first optical signal and a second optical signal. The optical receiver is configured to receive the first and optical signals and to generate first and second photoplethysmogram (PPG) signals resulting from the received optical signals. The processing element is configured to control the first optical transmitter to transmit the first optical signal the second optical signal, receive the first and second PPG signals from the optical receiver and compare them, identify a common cardiac component present in the first and the second PPG signals based on the comparison, determine a signal filter parameter based on the common cardiac component, and generate first and second cardiac components from the first and second PPG signals, respectively, based on the signal filter parameter.
