This
following image is of Xoscope output showing two timer circuits. They
have the same capacitors (47uF), but one has a 161.5k resistor while
the other has a 510.5k resistor. The difference in the resistors
causes different timing in each circuit. So this means to get the
timing difference we divide 510.5/161.5 which equals 3.16 then, look
at the picture to see the green line "which has the 510.5k"
shows one space, to every three spaces the blue line "which has
the 161.5k" shows.
I'm using both Tektronix probes, one model P6109, the other P6109B, on board 16 bit audio front mic input soldered to two BNCs which gives left and right.
Next,
maybe give the system a sense of direction.
