    To.Sgt wookie,

    I'm Just enquiring on that Square wave project, you suggested to the other member run the Signal through a Op Amp, unity gain voltage follower, and put a attenator on the input..

    Please Just for Learning purposes, what does a attenuator do.. I dont use op amps, but Have read up on them.. + whats the Primary Purpose of using a Square wave generator?.. (Basically)

    many thanks

    Welcome to the forums.

    Your question is a bit to the side of the original thread - http://forum.allaboutcircuits.com/showthread.php?t=35264 - so I have placed it in its own thread.

    Very briefly, an attenuator does the opposite of an amplifier. It makes a signal smaller.

    A square wave may be used for testing purposes, or to turn a logic element on and off.

    Like Beenthere said, an attenuator turns a signal of a particular amplitude and reduces it; ideally without changing the shape or form of the original signal.

    The most common use of a square wave is for providing clocks or other signals such as data for digital circuitry. However, they are also very useful in testing the effectiveness of signal filters, and many other uses.
