Abstract:
A type of data acquisition system of Laplacian ECG based on USB is introduced in this paper. The principle of hardware and method of software designing are explained. This system not only possesses very high CMRR, but also realizes the collection and transmission of Laplacian ECG signals in real time. This system is valuable in practice.
