Hello,

I am facing here the same problem when recording ECG with the ADS1299-6

I used channel IN1P, IN1N, and BIAS_DRV to measure ECG using ADS1299. I had set SRB1 on  and SRB2 to OFF, and included only channel 1 for bias generation with PGA gain =  2, But there were large amplitude of 50Hz noises and its harmonics (like 150Hz, 250Hz, etc), which was so large that it was impossible to observe the ECG signal. how can i reject the noise generated?

 Any suggestions? Thanks in advance.
