Actually there is a noticeable difference in the falling edges in most cases. This is exactly what you'd expect. The difference only looks marginal in your pictures because they weren't set up well to look for the effect, but it's still visible. Particularly in the top pair, the scope trace jumps from top to bottom on the left, but you can see the line on the right. The difference in dV/dt may be significant, which in turn could make a significant difference in capacitive coupling to other signals or radiation. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
