Almarg, isn't that a common misconception of what a square wave is? - 'A square wave is just a series of alternating positive and negative steps, with some amount of time between them.'

I always thought that a square wave was actually a sine wave with many higher harmonics added to the base sine wave, thus creating a continuous 'square wave'. Passing one of these square waves through a speaker intact is a test of the large bandwith of the speaker and its response time.

Thanks Al, I guess all that process control math (Laplace transforms etc.) has conditioned me (I have a Chemical Engineering degree)to only think in the frequency domain. :)

Salut, Bob P.
