How to convert a continuous signal into a square pulse?

[SparkyChem]

I think it should not be hard to answer this but i tried different methods, like using astable multivibrator but i am not sure if this is the right approach. Is there any easy way to do this?. The signal i have is +5volts and should be transformed into a 1 hz pulse. Any help?. Thanks.

The astable should be suitable. Or a 555 timer IC configured as pulse generator.

Do you need true bipolar AC, +-5V?
+-2.5V?
Or pulsed DC 5V?

You want to convert 5Vdc into a 1Hz pulse, is that correct?
Will this 5V power the circuit or is there separate power for that?

full wave rectifier will do.

I dont need a true bipolar AC, i just need a square pulse. High-low-high-low, this kind, as you said a pulsed DC 5V. What should i do?.

There is a separate power for that. By no means the input should be used as power source.

Wait, a rectifier?. No. I am talking about generating a pulse from a stable DC not the other way around.
