Method for driving pulse wave detection and method for pulse wave detection

The invention provides a method for driving pulse wave detection and a method for pulse wave detection. The method for driving pulse wave detection comprises the steps that first light driving signals and second light driving signals are generated and then utilized to drive a first light source and a second light source which are used for pulse wave detection respectively, so that the first light source and the second light source simultaneously emit light; modulated signals are adopted as the first light driving signals and the second light driving signals, so that output signals of a receiver which detects first light emitted by the first light source and second light emitted by the second light source can be separated into first electric signals and second electric signals after being demodulated. According to the method for driving pulse wave detection and the method for pulse wave detection, the scanning frequencies of the light sources in pulse wave detection can be improved, and then the sampling precision generated when ADC sampling is performed on the output signal output by the receiver can be improved.
