Hi,
Im trying to change a pulse train into a DC level, and im failing in all my attempts.
The pulse on or off time can be anything from 0.5s -> 3secs.
When the pulse line goes high, the output should go high. The output should remain high until the pulse line has been low for more than 3 secs.
I tried to use a 555 monostable, but once the pulse has gone low, there is no way to restart the time period.
Help!

Code:
pulse: __----__--_-_-_-------__---________________---_-
output: __-----------------------------------______------
