A modified saw tooth wave rather than square waves?????

[Guest guest]

A square wave is mostly used in Rife machines as it has been found to

be most effective in killing pathogens possibly due to a sudden rise

and fall time of the square wave and also due to its potential to

create harmonics. Square waves are known to produce ODD harmonics,

say a 1000 Hz will also produce a 3000 Hz and 5000 Hz and so on and

the strength of each harmonic is reduced in amplitude by the ratio of

their harmonic number.

A saw tooth wave also produces harmonics and contains not only ODD

but EVEN harmonics as well. The harmonics in a saw tooth wave also

are reduced in amplitude in the same manner as square waves.

The saw tooth waves appear to produce more harmonics than square

waves...so I wonder why do we not use saw tooth waves instead???

If the problem seems to be that the saw tooth waves do not have a

sharp rise as in square waves..can this problem be solved by using a

modified saw tooth waves....

I mean, a usual saw tooth wave has a straight diagonal ramp that goes

up and then suddenly drops straight down to zero. Now,can we modify

the frequency generator so that 2 simultaneous saw tooth waves are

generated at the same time with the same wavelength and amplitude but

the only difference being that one saw tooth wave has a straight

diagonal ramp that goes up and then suddenly drops to zero while the

other saw tooth has a sudden rise that goes up and then has a

straight diagonal ramp.

I do not have any engineering/physics background and I will

appreciate if any one on the group with more knowledge can throw some

light into this matter.

Thanks

This is most interesting.I hope to hear from the experts on this saw

tooth wave.

Square waves by definition have a 50% duty cycle and produce ONLY odd

harmonics this is true. But if you change the duty cycle to something

other than 50%, you produce even AND odd harmonics just like a saw

tooth. For example, at 33% duty cycle, you get a mixture of even and

odd harmonics.

One very big advantage of the square wave over the saw tooth is in

circuit design and efficiency. Square (or rectangular waves) are

easier to produce and much more efficient at driving power transistors

and mosfets. Using saw tooth waves would produce as much heat

dissipation in the transistor as the power produced by the plasma tube.

Thank you for the explanation.

Is it that only duty cycles below 50% produce even and odd harmonics?? What

about duty cycles above 50%. For example, some machines like GB4000 give an

option of using 90% duty cycle. If one uses frequencies say at 90% duty cycle,

what kind of harmonics does one get???

Thank you in anticipation
