tdi whites TONE IDEAS

[Orbit]

Does anyone know the frequency of the Threshold ,and if someone has a tonal scheme of the TDI ,or an idea that made the tone of the schematic detector whites tdi thanks for any idea ...thank you all and a thank you to everyone I've sent my sematic showed how people are ,thank you very much !

a promise to everyone that I would if I personally tdi bought and copied the tone of placed on geoteč forum just to spite some I promise to once again I always keep my promises .

[Orbit]

ideas?

The TDI tones are based on target polarity about the GB point. That is, a target tau higher than GB is a low tone, and a target tau lower than GB is a high tone. As the design is, adding more tones isn't very feasible.

I once did an experiment where I added a second "balance point" and tuned it to iron, for the purpose of making an iron tone. It was a mess of a circuit, and just didn't work well, so I abandoned it.

Thank you Karl ! if I understand TDI has a two-tone and adjusting the control geb emphasizes one or the other tone in turn control geb but there is an impression ,that has a VCO , Do you really have no or VCO . or by mixing two tones I get the impression that a VCO? Thanks for your response !

[Carl-NC]

Yes, it has a VCO. I should say that the 2 tones are a "rising" tone and a "falling" tone, not 2 constant tones.

Tanks Karl !

Hi,
I've got a question to Carl. Up to which value it works properly? How much we loose on the depth od detection using tone id?

Up to which value it works properly?

Not sure what you are asking.

How much we loose on the depth od detection using tone id?

Depends on the target... if its tau is close to the GB point then it can be completely notched out. Overall, there is maybe a 10-15% reduction.

Guite normal ! loss does not affect the loss of depth oscillator VCO. the loss of control affects geb ! VCO affect just to highlight the difference between bad conductivity just between between Copper and gold or gold and other poor conductivity of the material !
