yeah lol, can see that was abit confusing sry.
first of all, thnx alot for taking the time, and the quick reply.
Since i dont have to oppurtunity to test my circuit with the true signal, im testing it with a pulse signal thats got a freq on 2k.
the piezo sensors when nothing happens is around 0v , and when applied pressure sends out a signal with max peak around 1.8v before it drops to around -0.5v. the signal that lasts a couple of ms, before its setled around 0v again.
Im sry i cant give you any more information about the input signal then that, but the output should be the same signal, only 1 volt higher.
the supply voltage is not yet determined, gna create that aswell, but probably will be +- 12 V.
heres two screenshots of the circuits i have created so far. Here i use a +-5 volt suply. Not sure thats what you had in mind.
Sorry if my info isent enough, i should get more exact input info next week. But its rather the principle itself of "lifting" the signal one volt, than exactly determining resistors etc.
You think a opamp circuit is the right way to go?
Again, thnx for your time.
edit: only got one screenshot, the one with hight resistors on input.
