Re: Arbitrary Quadrature Encoder

Why are you guys using op-amps instead of comparators? Comparators output a direct digital signal. Response times will be better, since you don't need to worry about slew rate (not as if that was a concern in the first place)—something like the LM339 instead of the LM324.
