The Analog vs. Digital Frequency Debate - A Primer For Those Wanting to Know the Truth

   The current analog versus digital Rife scene is wrought with misconceptions and lies in the form of marketing hype such as, "digitally generated frequencies do not vary", implying that they do not have overtones and undertones. This would only be true if the frequencies remained digital. Experts and engineers in the Rife industry understand this. This is why digital frequencies from DDS (Direct Digital Synthesis) and DSP (Digital Signal Processing) are converted to analog before they are sent to the output of the instrument. These Digital-to-Analog Converters are called DAC for short.

   You can see in the diagram below that a frequency comes out of a DDS or a DSP looking like stairs. The signal then goes through a DAC or Digital-to-Analog Converter. Then it goes through a Low-Pass or Bandpass Filter to finish the analog conversion. The resulting signal is a very accurate analog frequency with all the overtones and undertones of that frequency. The analog frequency produced by a digital chip can be swept up or down with more accuracy than any old tube analog instrument. The most important thing to remember is that the frequency has to be converted to analog before it can be used.

   Digitally produced frequencies converted to analog are far superior to any signal that comes from an old tube-type frequency generator. Old tube-type generators are fundamentally very limited. If we want a frequency of say 2128.5, an old tube generator would not be accurate enough to give you that frequency to use. It could only give you 2128. Further, digitally converted frequencies allow you to sweep with far more accuracy than tube type instruments. Accuracy to a thousandth or millionth of a frequency is possible, even though this kind of resolution is not typically needed.

   This precise accuracy level of digital instruments is something that a purely analog instrument cannot achieve. Digital equipment can accurately produce extremely minute details. Dr. Rife told Dr. Stafford that he needed to be within one hertz of the frequency when using the low audio range, which means that an extremely close tolerance of accuracy is not necessary. If you can get 0.10 accuracy, that is all you really need. Why spend $4000 to $5000 on an instrument that is less accurate than superior instruments costing less than $2000? Additionally, tube-type instruments  can only reach the 20,000 to 30,000 cycles range, whereas, the GB-4000 is capable of reaching 12 MILLION CYCLES with pinpoint accuracy.
