SEIKO PULSE GRAPH is a pulse rate monitor for running training. This can be realized by the development of a blue sensing system and a twin FFT system. We have already published a blue sensing system to get a high S/N ratio^(1). The twin FFT system can separate pulse rate from motion noise that is generated during running. So we could realize the real-time pulse rate monitor system in the size of a watch. This paper describes the electronic circuit for a twin FFT system and an algorithm of measuring pulse rate.
