Hello
l need help on deciphering this block diagram . I would need a schematic from thid diagram. I don't have to much to go on
just this diagram, I lost the PDF file on it. But I do know it uses a 16pin mux switch it a multiplexer switch and a atmega164P micro controller to program the...
And that's why I need an experience ''Engineer'' to help. It seems no one on here has the expertise to understand what I need or doing.
If you did you might of answered in the first few post.
And what help have you given. NONE? So you don't have any positive help to give or experience.Just...
I'm not talking about circles. You are. ? I need real help. Not personal comments that doesn't even help me one bit. Not babble talk.
What I need is a non-resonance or resonant circuit or a schematic to what I'm trying to do.

I don't think you are so right about that.
This is where I think a resonance frequency tuned circuit
comes in to fine tuning the frequencies that I mentioned
in post #10 and #11.
This is where testing comes in to play.And Fine tuning
the signal being picked up and play back.And using
an...
Thanks for your input.But? What you are talking about isn't any thing you stated is what I'm trying to do.Every body has a comment.But just don't understand what I want or need. In this thread.
I just don't know how to explain it where a non electronic's engineer who could understand it.
And...
I can't change (L) in the LC resonance FQ of the Coil, that needs to be Fixed. Only the (C) I would be-able to change. for 1:12 range. But you stated that is not possible.
OK explaining X.
I want to make a magnetic field recorder. That could pick-up electromagnetic radiation emitting from...

What did you mean by this. That no resonant circuit covers a frequency range of 1:10 or more.
frequency range of 1:10 or more. Explain this please.
You are right, there's no tool for the spiral coil, but a formula. I get e.g. N=85 for R=2.4 cm, w=2cm.
I don't know how that formula works. So I don't know how to calculate for the flat coil.
How did you get N=85 R=2.4cm and W=2cm. How did you arrive at these values with the formula.
I may...

I may not understand it.
Digital:min. pulse width > 0.01 msec. Analog: all significant frequency components <...
I don't get the answer for a flat coil of 400uH with this calculation tool.
Maybe the spiral flat coil might be a better choice.I don't know?
There's no calculation tool to enter specs for a spiral flat coil.
This is the calculation I get with the Single layer short Solenoid.
R=45
l=0 flat...
1.In post #1 I need to make this antenna.I still don't know how many turns it take to make a 400uH
pancake flat coil. How long would the wire be for the number of turns I would need,
2. How do I get a variable frequency of 1KHz to 12KHz with the antenna coil in Post#1.What capacitor
value...
Can anyone Help who knows about there antenna's. T hey moved it here the thread. Don't why. I got a reply from a poster.But its gone. When it was moved Here.
Help?
Found this antenna on yahoo sometime ago can't find the site again.
I need to know how to make this antenna.
I need to make a 400 micro Henry antenna like the one attached.
Using 26g stranded wire or 20g magnetic wire.Which one would be better.
How many turns with it take to get with either...
I don't understand this at all what do you mean state diagram.Or even know where to start.
And how many coding methods can there be if its either DTMF OR binary ones and zeros.Digital 0-9.
The DTMF decoder chip or circuit I can do.But the rest you mention I would need a circuit diagram to work...
Sorry about that blocking diagram it was the best way I was able to
explain it.
Its not DTMF. So it must be 1 0r 0 binary code but digitized as an analog looking
signal.
But if it is DTMF. Assuming that it is. Then how do THIS.
I need more help with the transfer of the DTMF TO registers and...
