Hello
I have a pulse wave coming from the photo diode, with T(ON) = 50-60us, and total time period is approx 20ms. Since this is too short a period (T1) to be detectable I want to increase it to 5ms, keeping the total time period same, that means I want to multiply the duty cycle by 20 to 30, how can I achieve that?
I have tried RC delay + Schmitt Trigger, but it is not working since my need is 20 to 30 times.
Kindly help

Regards
Rahul
