How to change a abs/rectifying level ? From 0 to for example 0.1

Hi,

 

I have a simple demod program to demodulate a signal from LVDT and I use abs function to rectify the secondary coil signal. Is there a simple way of changing "trigger" level of rectify function so I could "mirror" signal let's say at 0.1 instead of 0 ?

Not sure what you mean exactly, can yougive some examples of what you would get as a desired output? For example, if you could offset the "trigger" by .1, what would you get if you fed it an array containing the values -0.1, 0.0 and 0.1 ?

I agree with Mike that it is not clear what you want.

 

One possibility may be to add (or subtract) your trigger threshold to the array before doing the absolute value.  This should have the effect of moving "zero."
