Output first zero of a signal?

Is there anyway to output the first time at which a signal is zero (excluding at t = 0)?

You should be able to do this in Simulink with some combination of the Clock, Compare to Zero and perhaps some other basic Simulink blocks.

Answer 2

[Azzi Abdelmalek]

use a "switch" block with three inputs

1. a signal from "clock" block (input3) %to get time
2. a signal from a "constant" block (input1)
3. your signal (input2)

set a condition in a "switch" block, to select which signal will be the output of switch block: the constant 0 or the time from a clock. you have just to ignore when the output is zero

Thanks for that help, I have another related question though how would I go about finding the time difference between each successive zero for the first 0.2 seconds of the simulation?
