Thanks in tones ..for all the idea.
The signal is not 50% duty cycle. This signal is coming from other
card. I need to glow a LED if square wave is present. Voltage level is
digital i.e 0V and +5V. Basically if there is toggle in the line I
need to drive low and if no toggling drive high.
If this detection can be done using simply digital circuit along with
capacitor and Diode will be great.
Thanks in advance
