发明名称 Method and apparatus for measuring biological signal
摘要 An apparatus for measuring a biological signal of a body, the apparatus including; at least three interfaces which obtain signals from the body, a signal application unit which applies a signal having a frequency which is higher than one of a frequency of interest of the biological signal to one of a first interface from among the at least three interfaces, and one of a plurality of internal elements of the apparatus, a feedback signal generation unit which generates a feedback signal from component signals generated due to the applied signal, wherein the feedback signal generation unit generates the feedback signal using a signal obtained from at least one of a second interface and a third interface from among the at least three interfaces and an input control unit which receives the generated feedback signal and controls a signal input from at least one of the second interface and third interface to an amplifier.

主权项 1. An apparatus for measuring a biological signal of a body, the apparatus comprising: at least three interfaces; a signal application unit which applies a signal having a predetermined frequency which is higher than a frequency of interest of the biological signal directly to a first interface from among the at least three interfaces, and one of a plurality of internal elements of the apparatus; a feedback signal generation unit which extracts component signals from a signal obtained from the body using at least one of a second interface and a third interface from among the at least three interfaces and generates a feedback signal for removing motion artifacts based on the extracted component signals wherein the feedback signal generation unit comprises a demodulator which demodulates the signal obtained from at least one of the second interface and the third interface using the signal applied by the signal application unit; and an input control unit which receives the generated feedback signal and controls a signal input from at least one of the second interface and third interface to an amplifier to remove the motion artifacts included in the input signal by using the feedback signal, wherein a difference between a frequency of each of the component signals and the frequency of the applied signal is within a predetermined range.
