By "average" I mean > exactly what you think I mean: add them up and divide by the number N. So basically, it means to use quality sampling instead of quantity sampli= ng. Just pick an arbitrary pattern (that hopefully doesn't synchronize or bea= t with your samples) and smart-sample=AE your way to success. ;-) > >Also I hear/see the term > >"integrate" and am not completely clear as to what this means in the > >context > >of EE and data samples. > > "Integrate" in the case of discrete samples just means "add 'em up". > Same as the averaging technique I mentioned above. That's simple enough for my pea-brain. ;-) Why don't they just say that?= ?? I'd learn this stuff faster if it wasn't for the language barrier. ;-D > Michael V (still trying to be helpful...)
