Bio potential detector measures the electric potentials on the surface of living tissue. Bio potential detection is useful in many medical application such as ECG, EMG, AND EEG MONITORS. Therefore is also useful to have the ability to test the Bio potential detector by a bio potential simulator.

 The project goal is to implement a controller of a bio exponential simulator. The controller should control the signal at the output of the simulator.

 The code on the FPGA shall be divided to two main parts.  The first part is the calibration of the D/As’ m and c registers. This registers should allow to digitally set the slope to 1 and to eliminate the bias.  The second stage is the normal running of the system, which continuously reading values from the dram and sending them to the D/As.

 FPGA that can be programmed using LABVIEW  LVDS card(for debugging)  PCB with 4 DACs and 1 ADC
