The topic is simple, but I really need a hand on the design:
I have a car that has a velocity sensor, and what's needed is the acceleration. Well, from Newton's law of motion (or somethin' like that) we have:
a = dv / dt
So I thought a simple voltage differentiator would do the job, assuming that the velocity sensor give the speed as an increasing (or decreasing) voltage. But that's just nice so far. And that's how far I got: I have to use just capacitors, resistors (variable or not) and an op-amp (of course). Guys, if any of you know a good method to board this kinda problem, please I need some help! :lol:
