I just wanted to point out that square waves, although they have a nominal frequency, are really composed of an infinite number of sinusoidal signals. The edge of a "theoretical" square wave is an impulse with infinite frequency (i.e. vanishingly small period). I've attached a pic I took with my scope last weekend of a 24.576 MHz clock (crystal oscillator). Notice that even though my scope has 100 MHz bandwidth, it can't reproduce the edges. However, the fundamental frequency is obviously there.
