Hi Shortbus,
You are correct, and I just tumbled to that situation while sorting this thing out in my workshop. The waveform that I have connected to the 393 is coming from pins 2 -6 from the 555, not the square block output from pin 3. I had been looking at the thing too long.
What I need now is help in configuring an Integrator circuit, which is made up of an inline resistor and a capacitor, with the capacitor being connected after the resistor and then to ground.
I'm also working specifically with a 16kHz frequency, which should have something to do with the value of those two components. As the triagular output of the 555 has sloped sides to it, I would expect the waveform of an Integrator should be roughly the same.
Again, thank you for your response and hopefully help in finding these component values.
