Aiming at the characteristic of the ECG signal,a design of ECG signal acquisition circuit is provided. The amplifi?cation and filtering circuit is designed,and they are tested and analyzed one by one,finally clear and accurate electrocardiogram is obtained. The circuit can be used in portable ECG monitor for its small size,low cost and low power consumption. The obtained electrocardiogram can provide the basis for doctors to diagnose cardiac disease.
