Abstract: USB (Universal Serial Bus) has been a standard interface for PC,
which can transfer data in high-speed among PC and external devices, and
have the virtue of bus power supply etc. In this paper, the running
performance and characteristics of PDIUSBD12 produced by PHILIPS Company is
introduced, and the principle of hardware and method of software designing
are explained in data acquisition system for dynamic ECG.
