Help Needed: Frequency to Voltage Converter Knowledge

Click For Summary

Discussion Overview

The discussion revolves around the principles and specifications of frequency to voltage converters, particularly in the context of an electrical engineering project. Participants explore the underlying concepts, circuit components, and practical applications related to this topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses confusion about the principles of frequency to voltage converters and seeks assistance.
  • Another participant suggests visualizing a voltage versus frequency graph of components in LR or CR series circuits, indicating that reactance functions like a variable voltage divider.
  • A participant requests more detailed information regarding the specifications of frequency to voltage converters.
  • One participant asks about the specific frequency range and voltage requirements for the converter, emphasizing the importance of consulting circuit textbooks for foundational knowledge.
  • A later reply mentions finding a specific frequency to voltage converter (ADVFC32) that meets project needs, indicating progress in the discussion.

Areas of Agreement / Disagreement

Participants generally agree on the need for foundational knowledge and specifications related to frequency to voltage converters, but there are multiple approaches and suggestions regarding how to proceed with the project. The discussion remains open-ended with no consensus on a single method or solution.

Contextual Notes

Participants reference the importance of specific frequency ranges and voltage outputs, but details on these parameters remain unspecified. The discussion also highlights the need for further exploration of circuit components and their specifications.

hello! Nice to communicate with your guys! I'm a student who is studying in double E subject. I found some problems when I'm doing the new project this term. Is there some one can help me to say something about the principle of the frequency to voltage converter? I'm really confusing with this part of knowledge now... thanks a lot for helping! :confused:
 
Engineering news on Phys.org
KISS - think of a voltage versus frequency graph of the components in an LR or CR series circuit as driven by a voltage source. Hint, the reactance works like a variable voltage divider.

Now rectify with a diode and a cap to smooth out the waveform...

You choose the reactive component to change whether the voltage increases or decreases in frequency.

That help?

yeah, That make me feel better about this~thanks,however, can u tell me some more details about this? For instance, something about the specification of the components of Frequency to voltage converter?
 
Well, what frequency range and voltage are you looking to input/output?

The rules of the forum are to assist, not provide solutions.

I'd say the first step for you is to look in your circuits book for the series LR or CR circuits and decide which one provides a voltage curve you can use. Obviously there are other ways to do this as well, if you find one you could explore that too. I suggested a simple start that should be in your textbook with plenty of examples.

Thanks for helping me! And I have found one Frequency to voltage converter, which fit for our project needs. And I have got the specification of this converter, ADVFC32. Thanks a lot for help again~
