A Simple Bioelecrical Signal Simulator for Measurement Device Testing
نویسندگان
چکیده
− A very simple PC based system for simulation of bioelectrical signals is presented. In addition to a regular PC with an audio card and the constructed software only few passive components are needed to accurately mimic the waveforms of the original recorded bioelectrical signals stored in the PC’s hard drive. Alternatively, the simulated signals that are generated from the original recordings by Matlab can be played back with an mp3-player. Due to the nature of our method and the bandwidth limitations of PCs’ audio card, the system is not suitable for simulation of high frequency signals but for bioelectrical signals like electrocardiogram (EKG) the method suits very well.

اندازهگیری پیچش استاتیکی و دینامیکی محورها- کاربرد ویژه در پایش ارتعاشات پیچشی
Strain gage mounted on the surface of the shafts with specified directions are one of the common methods for measurement of the torsion in shafts. The most critical problem in utilization of this method, particularly in the online monitoring of torsional vibration and instantaneous torque in rotary systems, is due to its signal transfer process. In this paper, a simple, practical and feasible m...
