The Life Fitness Lifepulse™ system uses complex software algorithms which require a microprocessor capable of performing digital signal processing (DSP) functions for heart rate. The term digital signal processing, or DSP, refers to the process of digitally sampling a signal, converting the sampled signal into a stream of numeric values, then processing these numbers using mathematical techniques to bring out features of the signal not otherwise observable.
Lifepulse™ uses DSP techniques to perform filtering and frequency analysis to calculate the heart rate. And, because DSP algorithms operate on a stream of data enough data must be collected before the analysis can be started.
Depending upon the noise and signal level a Lifepulse™ value can be displayed in as little as 4 seconds. Generally speaking, the longer you hold the Lifepulse™ sensors the more accurate the results
