hello everyone, here is my problem

i do not know how to invert a signal.

actually, i have this signal which starts by a rising edge
and instead i want this one which starts by a falling edge
i don't know if it is possible to change the first one in order to get the other

thank you in advance.

Want to do this with analogic electronics ?

What about using a transistor ? (you will not get 0V however byt 0.2 I guess)

Hummm; interesting...

I propose the classic 'put the screen upside down' :)

lecougar, use a 74LS04 inverter: http://www.datasheetcatalog.org/datashe ... 54LS04.pdf
