I have used the view - separate curves option. I can split the curves up to see vf1, noise1 and vsig but there is no noise2?

I think I get it. I did post a message with my interpretation. I was unsure how to get the wave to show. I have now.
I'm ready for the next bit.
Thanks
Just
However, from the results VF1, seams to be unaffected now by the noise??
Please can you explain..

I get it. Is that why ECG machines have three electrodes. 2 grounds(1 ground being placed away from the heart so as to have no signal from the heart) and a signal. The 2 grounds are fed into the non inverting and inverting side of the amp. The signal will be only sent in one side.
I understand the concept of the noise being cancelled out now I think.
So we don't need caps at all ????

Horses got fingers? I knew chickens do, becuase they are tasty when deep fried, but horses?If there is any way possible to duplicate the finger tip Optocoupler concept on a horse...
Hi Bob
I think your knowledge of horses is as broad as mine is of electronics!
Seriously though, I did consider using the optocoupler Chris mentions. I thought about putting it on the horses ear. It's ears have a good blood supply and are thin. However horses in general hate anything messing with their ears and the attachment of a sensor is likely to make his heart rate race!
I am starting to realise why at present there is no cheep and simple method of measuring a horses heart rate electronically.
