    Problem in an ECG circuit

    What should I do to bias the inputs? A resistor between each of them and virtual ground? I can't see the bias in the ECG circuit you posted.

    Problem in an ECG circuit

    Hello, I am trying to make a simple ecg/emg acquisition circuit. I am using 2 of these https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/ active electrodes for the differential signal and this https://www.olimex.com/Products/EEG/Electrodes/EEG-PE/ as a passive DRL electrode. My...
