Contact type pulse measurement device for sports equipment, such as treadmill, has signal processing unit which displays pulse data on display device after signal is processed and fed back to associative processing unit

摘要

An associative processing unit receives a signal processed by an analog filter/amplifier to selectively process and compare a parameter setting. A signal processing unit displays pulse data on a display device after the signal is being processed and the signal is fed back to the associative processing unit for setting a system parameter. A bio-potential sensor is coupled to two active sensor electrodes having corresponding opposite polarities and respectively coupled with a pulse measurement device by conductive wires. A bio-signal measurement receives a signal transmitted from the bio-potential sensor, and is coupled to a negative feedback difference common mode signal and a buffer/balanced circuit. The buffer/balanced circuit is fed back to the negative feedback difference common mode signal, and both negative feedback difference common mode signal and buffer/balanced circuit provide a circuit with a self common point electric potential. The analog filter/amplifier receives a signal transmitted from the bio-signal measurement.
