摘要 介绍了一种基于USB的Laplacian心电信号采集系统,给出了详细的硬件和软件设计。实验证明,该系统不仅具有很高的共模抑制比,而且能够很好地实现Laplacian心电信号实时采集和传输,具有一定的实用性。 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.
