as i am still writing my extended essay about analogue integration vs. digital, another problem has emerged.
My collected data is really not, what it should be. An amplified sin-curve should look kinda streched in the y -axis, shouldn't be? (i.e. y=a sin(x), where a is the amlification.) Well, what i got, is really y=sin(x) + a ??? :? . is that normal? HELLLP!!! The curve is just shifted up/down on the x-axis, that doesnt seem right to me at all.
Well, I hope, someone will be able to help me out of this mess, thanx a lot guys!
