#102743 - Using the "time derivative" of signal Responding to: ???'s previous message |

Kai, I like your idea, but will that not add a short delay to the triggering, as in the note can't trigger until the clipping stops?{ Yes, this can happen, when the puls lasts to long. One should have a look at the pulse with osci. Anyway, what I stated in my reply was only what I think is accomplished in the link you gave. I would try to solve the issue a bit differently: I would use two comparators with thresholds set at 1V and 2V (or so), and measure the time the rising edge of signal needs to traverse. This would allow you to determine the punch of signal from the slope of signal, means to have a look at the time derivative. The advantage would be to gain information about the punch right at the beginning of pulse, so that any delay is minimized. Kai |
