Hi Klaus
Yes I did connected all the Vr connections and verified the 2.5V.
I have used filtering in supply voltage by adding capacitors and have generated the supply voltage from a battery to minimize the power line interference.
I am not sure about right leg circuit. Actually I...
I have been trying to view the ecg waveform using the ic ina321.
first of all I tried by adding a resistor across the 100k resistor in the input side and verified the output of ia321 as a pure dc signal. Then I connected the electrodes and at the input I got sine waves with peak to peak...
