If you have multiple signals to process, you may want to look into a multiplexer IC chip. They are programmable and depending on the inputs, you can get a certain output. That might aid in de-multiplexing and multiplexing your inputs and outputs.... [/quote] Thanks, I am not new to electronics but the more advanced concepts I still need to learn and well, fail a few times before I get it right. My bucket of scrapped breadboards is proof of this, lol. But seriously, this is awesome advice, thank you. I was thinking.... the two forms of saw tooth are almost exact opposites. Take one that rises in volts rapidly (the wall) and declines gradually (linear) to 0v. The other drops gradually to -v and returns to 0v rapidly. In essence they are true opposites. But it is not that exact, they over lap slightly (at most 1/3rd) and that over lap causes problems in the comparators. I get alternating high low and the low is the other saw tooth crossing the reference. Plus, the over all voltage of the signal can shift 3-4 volts by tuning the setup (I have to keep some of it confidential atm). The waveform shifts pending the photo bias, interference patterns high, low and all in between. A unique function of this interferometer. SO there is another strike for a comparator. Unless I can get the window comparator reference lines to shift with the over all signal adjusting. I hope this makes sense. I recently had great success by converting an INS AMP into a transimpedance amp for the photodiode. Works great because the feedback resistors can remain fixed and therefor ground circuit can shield them easy. It makes a VERY clean saw tooth. The saw tooth is interesting because it is created in the photon state. How my invention works, that is the impact on the laser beam into the sensor. It makes saw tooth waves. What made us jump, including the patent lawyer, was the ability to discern which direction the target is moving WHILE providing the fluctuating interference pattern to measure half wavelengths. NO interferomter to date does that with out chopping the signal to achieve a type of feedback. Like a Bragg Cell, or some other independent sensor for direction. Mine does it all in one. And we believe it will dominate a 120 million/year market. CHA-CHING! [/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.
