Many thanks for the reply. Let me put it this way. Let's say I have a
noisy data that follows a sinusoidal curve. This data is in time
domain. How can I get a smooth sinusoidal curve?
I can also put it in a different way. My data is a sinusoidal curve
with say 2mV peak-to-peak dynamic noise.
How can I get a smooth clean sinusoidal curve.
I hope I described it in a clear way.
Many thanks,
Jenni
