Hardvare Design for Processing Medical Signals

This article suggests some ideas of a hardware design for processing medical monitors. As example it will be ECG monitor. Its configuration is envisaged for use with a personal computer (PC). The article demonstrates that significant improvements can be achieved with simple hardware combined with attention to software. The improvement in this example is by no means at the optimum level; it should be possible for a dedicated designer to significantly improve the results. Additional improvements could be made if code with different filter frequencies or other special characteristics were to be implemented. The code memory of the ML is flash based, allowing such customization to be made after a product using it is manufactured or even as the patients needs change. An ultimate result could be compact, inexpensive ECG for a potentially large-volume market.
