My little brain has been thinking a lot about comparators lately. I was just thinking of a concept where some comparators coupled with the wonderful MOTM-820 VC lag might make nice "multiple gate delay." Here is the idea: Feed the gate signal into the VC lag. Set the down lag time for zero. Take the output and run to 3 comparators. Each comparator is set to turn on its output at a progressively higher level. The output of each comparator is used as the delayed gate. So, now I have 4 gate signals turning on a 4 different times - the original gate, and the 3 comparator outputs. The up lag time sets the overall delay range. The comparator set points set the relationship between gate times. Since the 820 is set for lag only in the up position, all gates would end at the same time. The more I think about comparators, the more useful I see these generic and apparently useful utility circuits. I guess I am surprised that more people on the list have not talked about them. Of course, I have to admit to absolutely no modular experience before MOTM. So, I run into ideas that are "new" to me that may be completely old hat to you guys with more experience. Stooge Larry
