Abstract
There are provided an apparatus and a method for measuring pulse waves. The pulse wave measuring apparatus includes a receiver configured to receive pulse wave signals sensed at at least two points of an object; an analog signal processor configured to amplify a voltage difference between two pulse wave signals from among the received pulse wave signals and integrate the amplified voltage difference; and a digital signal processor configured to analog to digital convert a value of the integrated amplified voltage difference and obtain, from the converted value, a pulse transit time between the two points corresponding to the two pulse wave signals.
