On the test point I am looking for 0 to 10v signal. The part of the circuit that is indicated by S1 actually is come comparaters and nor gates witch result in Either gnd or +15v or gnd. The Charging circuit is actually a constant current cuicuit feeding C1 via R10.
My problem is the signal nevver reaches 0 volts (as shoun on the trace. I can compensate in the comparator for this), but I really want 0 volts. Changing the 1k (R3), but that changes the decay rate and the current.
Does anyone have any sugestions?
