Can anyone send me circuit diagrams and working of voltage to frequency converter and frequency to voltage converter? Thank you in advance

 

Look up the LM331 - the datasheet details how to use it in both configurations.

 

Lm2907 F to V chip.

 

Hi
Voltage to frequency converter can also be called a voltage controlled oscillator.
refer the wikipedia page for more details...................http://en.wikipedia.org/wiki/Voltage-controlled_oscillator
or you can refer this link too for circuit diagrams..................http://circuitsplanet.blogspot.in/2015/02/voltage-controlled-oscillator.html
for FVC...................................................................................http://circuitsplanet.blogspot.in/2015/02/frequency-to-voltage-converter.html

 

I think you better talk some more what you want to do for that F to V then when the members give you the solution may easily to get to target.

I'm with him.... the frequency-range that you need will have a huge impact on the topology/effort required

 

What range of frequency are you looking for?

If you want dead simple - just use the 2-transistor astable multivibrator.

The 2 high value resistors that feed the transistor bases and form the R part of the CR timing networks usually go to Vcc in a fixed frequency implementation, You can also common those 2 resistors and take them to Vcc through a pot that can vary the frequency - or you can return the tops of those 2 resistors to a voltage that controls the frequency.

The 331 is also equivalent to an RC145...something or other.

Sharp made a version. AFAICR; "331" fits into their longer part number.

These chips were all the rage in the early days of multisync VGA - I haven't checked whether any of them are still obtanium nowadays.
