Any Ideas on this implementation

Hi,

I don't know if this is possible but I need this kind of implementation on my circuit.

Say, I have a signal with a 2uS pulse width for high and 4uS for low pulse but I need to increase the pulse width from 2uS to 20uS (high) and from 4uS to 40uS (low). The duty cycle is 50/50.

Anybody has any ideas on how I can make this box/circuit in such a way it will change the pulse width as explain above.

thank u.

The way you've defined input and output, the duty cycles are 1/3, not 50%. Perhaps you could explain it a different way.
 
the duty is about 1/3. Duty cycle is dependant on the high time and the low time.

It is 1/3 because 20/60 (60 = 40 + 20) = 1/3.

You can make a 2-transistor astable multivibrator. Check out:

It shows you how to make one.
