VCO(VOLTAGE CONTROL OSCILATOR)SUITABLE FOR U R PROBLEM

DEPENDING UPON TUNNING TUNNING VOLTAGE THE OUTPUT FREQUENCY OF VCO VARIES,CHOOSE THE VOLTAGE CORRESPONING TO THAT

Yes,
VCO are what you need. The kind of VCO LC or ring osc depend on your application.

thanks alot , dear friends .

i want to define my project for you . :!: i hope you will help me .

i want to give about " 4 VOLT " from a battery or same like this , then convert to frequency and send to another Device - then in this Device convert frequency to voltage to upstart this device .

really , i want to transfer voltage wireless , by This Way .

* * i need a detail and completely information to run this think . ! ! :idea:
i am beginner :| :|
please tell me surely ,how i can do this project .

*myself founds these ( please see ) : :arrow:

You're looking to do a lot more than convert a voltage to a frequency.

What you seem to be wanting to do is transmit power wirelessly, not impossible - but not something you want to do indoors.
I don't know much about this area, so I can't really help, but this doesn't seem to be a voltage to frequency problem you have.

Remember to power a circuit, you need Voltage and current. You could have a battery on the other circuit to derive your power from and just transmit a voltage via a frequency, but this surely voids the point of what you're trying to do as I understand it.

we are thinking to solve ! and reach invention

thank you very much :D . i am thinking :idea:

this myfriend'idea , Quote for you :

hamid_h552 said:
hi.
you can use FSK modulator and demodulator s which are available in packages.
in FSK modulation you have two levels of voltages which you give them to a VCO (voltage controlled oscillator).
then it gives you two different frequencies.
then in demodulator this frequency is translated to the voltage wich you have fed to FSK modullator (or VCO)
this is suitable for wireless communication too.

Are you wanting the voltage to power a circuit wirelessly?

If so, none of the affore mentioned ideas will work.
