The waveform of a current describes the shape of one cycle of the current. The frequency of a current is how many times one cycle of the waveform is repeated per second , and is measured in hertz (Hz).

A square wave behaves the exact same way as a sine wave, in that as its fundamental frequency increases, you will see more cycles in a given amount of time . Square waves theoretically have infinite bandwidth.23 Eyl 2014
