[quote:-Adam-:MV8zNDY4MjI3XzYxOTk3NjkzXzc2MzBENjgz] It is sensing an interference pattern of light. Gets brighter and darker pending the line up distance. Interestingly, as it is unique, the signal reverses its shape when the target reverses direction. But it will vary in frequency as it is measuring a real time object. From almost DC to the IC's skew rate. So that presents challenges, naturally. But at least this type of device is glorified around micro motion, so digital analysis is easily up to speed. I suppose it would be wise to just use the Arduino and program the filter. It would give me many options. Thanks everyone, I have a lot to research so far. [/quote]
Original Message
Is there any way to separate or filter out a sawtooth wave dependent upon which direction the saw tooth edge is?
ie, one part lead rises sharp and tapers for one signal and the other signal has a leading taper then a sharp drop in voltage.
I do not want to filter frequency, already have a passive low pass to cut high freq noise.
Just need to separate the two signals. (or omit one and then buffer, omit the other)
I am completely baffled on this one.
