Square Wave vs. Sine Wave 

Another debate within this field is "which wave format to use?"  Before the newer instruments were developed, all the generators output only radio frequencies, or "RF".  When emitting these radio frequencies, the sine wave format is produced.  Basically because this higher frequency range (in the millions of pulses per second, or hertz), creates a wave form that is naturally rounded at the top and bottom.  It's more difficult to create very sharp signals at this high rate of oscillation.

With advent of the newer Crane/Marsh design, the rate at which these signals are emitted dropped substantially into what is referred to as the Audio Frequency range. (this was not a desired design aspect at the time.)  With these lower frequencies, the signal can be very sharply turned on and off, as seen below. This square wave design is used when running the lower audio frequencies.  One important reason is because it helps to better create entrainment between the signal being emitted and the target. The principle of entrainment is at the very foundation of this entire science. 

Entrainment is defined as the "tendency for two oscillating bodies to lock into phase so that they vibrate in harmony."  It is also defined as "a synchronization of two or more rhythmic cycles". The principle of entrainment is universal, appearing in chemistry, pharmacology, biology, medicine, psychology, sociology, astronomy, architecture and more. 

 In the radio frequency range, a sine wave pattern is generated.  (above 40,000htz)

In a lower audio range , a square wave is desired ( Below is 40,000 htz )
