The purpose for researchers in medical electronics field, in signal processing and information field is to provide powerful and low-cost systems to help doctors to make his specific spots. In this paper, a biomedical monitoring system is proposed based on LabVIEW FPGA. This monitoring system has the advantage to acquire and analyze several physiological signals. The Electrocardiogram (ECG), Electroencephalogram (EEG) and Electromyogram (EMG) signals are recorded from respectively the heart, the brain and the muscle. Then, each signal is amplified, filtered and displayed on the computer. The designed system can be used to determine and monitor some physiological parameters. This system is designed using a National Instrument data acquisition device. The signals processing, the display as well as the user interface are managed by the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) with the specialized module LabVIEW FPGA. The field programmable gate arrays (FPGA) configuration has not been made by Verilog Hardware Description Language (VHDL) but rather by a graphic programming with the LabVIEW FPGA. The programming by LabVIEW saves a lot of time and can be easily verified in the case of a bug. This system allows the determination of some physiological parameters and can be used as a powerful vital signs monitor.
