| Abstract: | A measure of system design for collecting and processing of heart sounds signal based on Matlab and 16 bit low consumption MPU was introduced in this paper. This paper also provided a method of resolving the bottleneck that Matlab needs a lot of data to process, which is allocated serial port buffer by Matlab when it was communicating with the MPU. The method also realized the dynamic show of datas on no matter time-domain or frequency-domain, digital filtering, save-load, and some specific approaches to control the slider bar for the show zone. |
