I need to build a circuit that changes the output for a certain time when my signal exceeds its range.
I have a kHz-bandwidth signal (incorporating DC) that is part of a control loop and sometimes it goes out of range (+/- 15V). When that happens, I want the output to switch to 0V for a certain amount of time (10 ms to 2 s) and then change back to the actual signal.
What I found so far is a Window Detector circuit that triggers when the signal exceeds the range and a 555 timer circuit which can keep the signal on high for a certain time. I do not, however, know how to switch between the actual signal and 0V when the output from the 555 timer is set to high.
Thanks for everyone's help, I am quite new to designing actual circuits.
