hello
I want to do something similar to a missing-pulse-detector, but I want it to detect also steady signals
so I basically want to output high when the input is not switching up/down (up is around 1 second, down may be from 0.3s to 10s... but it doesn't need to be so exactly because it just should trigger if it's not switching for more than 15 seconds)
I'm trying to avoid using a microcontroller, so maybe 555 can do that?
input:
_--_--___--_--______________--___--_-----------------_--_--
output:
______________________-----_________________------______
