hello... this may seems a litle strange, but i need to convert some input that is 4Khz and 10% duty cycle to a clean DC
**broken link removed**
as you can see in the diagram, the pulses are 'low', so i want the output of this circuit to be 0 when there are puses detected, and 5v otherwize.. it's kind of a simple data holding...
i want to keep it simple with capacitors, i know there are many many many ICs to do the job. Please don't suggest any.
precision is not a problem, specialy about the time at which the output will swing from a state to another.
If it works, is there any danger the capacitor sends destructive currents through the diode D1?
Again, if the idea is correct, what or how to calculate the value of R1 and C1.
I case you want to know, the input of this circuit is actualy the ouput of a proximity sensor...
thanks in advance...
