Abstract

The present disclosure provides an electronic device and a method of measuring pulse adapted for the device. The electronic device includes a capacitive type touch control unit to sense the change of pulse and the capacitive type touch control unit includes a capacitor. The method includes steps: detecting a pulse of a user in real time and sampling the pulse every sample period, measuring charge-discharge time of the capacitor according to the sampled pulse at each sample period, counting a capacitance value of the capacitor according to the charge-discharge time corresponding to each sampled pulse, and forming a first wave form showing all counted capacitance values of the capacitor. Doing a spectrum analysis of the all counted capacitance values and performing a Fourier Transform to obtain a second wave form of pulse frequency-amplitude, and displaying the second wave form.
