I am a little bit confused. i know that you can only step up/down the voltage of an AC current, and you can turn DC into AC using an osscilator, something as simple as a 555 astable. Thats fine.
BUT: how is a square wave AC? it is only changing for a very short ammount of time. For the rest of the time the wave is either 'High' or 'Low', i.e. it is not changing, making it DC for that period of time....????????
Can someone explain how this works?
Thanks
