Adaptive noise cancellation

[marp84]

hi bro i need to know what is the Adaptive noise cancellation ?

How to make the Adaptive noise cancellation for remove 50Hz from our body to make the good signal at ecg?

if there is additional pallete what's that?

If you know the noise is at 50 Hz, just use a 50 Hz notch filter.  Look up filter on the labview help for more info.

I know you have been working with your ECG project for a long long  time now. Since I have not seen any ECG screen shots from you is it hard to give any specific help. But one advise is to start with your measurement hardware/electronic. If this is not properly engineered, the result may be extensive noise pickup. A digital filter may help. But it  do not work as a magic wand, you can whisk away all you noise with

Yes, it would be a lot easier to help if you post your code and hardware details.  Otherwise, we are left guessing as to the best approach.
