Description
For example, a pulse will be shortened to about 67 us in the current configuration.
You can change this by varying the values of R1, R2, and C1.
Quick explanation:
When the input is high, C1 will charge through R1.
For the output to be high, the input needs to be high, as well as C1 to be below a certain limit. This is achieved by using an AND-Gate.
If the input is low, C1 will be discharged through R2. For this, a NOT-Gate is used.
DISCLAIMER:
I am only a beginner when it comes to circuits, but I thought this was worth sharing. :)
I don't know if something like this has already been made (perhaps with another name).
If you don't want a clean digital signal, you can of course stop wasting your time on this site and just use a simple capacitor.
