Help with obtaining a specific pulse

malsch said:

Hi, I have a 1Hz pulse and wish to obtain a very short pulse at the low edge of the 1Hz pulse. The following is what I'm referring to:

Since I cannot use a capacitor, I was thinking maybe something with flip flops but I'm still a bit stuck.

Thank you

So you can't use a capacitor? You need a delay of some sort; one way is to use an RC or RL delay, another is to use a gate delay.

For the gate delay method (i.e. no cap), connect the input signal into a NOR gate and inverter as shown in the attached diagram
