I have a signal (drawn in the image). I want to filter the small "spike" away and just keep the 2ms signal.
How can i do that. With a capacitor?
How do i figure out what value i need then?
The levels are 0 and 5V.
The scematic looks like this:
15V ---[1Mohm]-------------[470Kohm]------GND
................................|
................................|
GND---[Zener 5.1V]-- |-----[cap?]-----GND
................................|
................................|
.............................[PIC]
Edit:
Ignore all the "dots".
