Frequency of receivers to receive each others transmission.

Click For Summary
SUMMARY

The discussion centers on calculating the frequency to which receivers should be tuned to receive transmissions from two transmitters operating at 17.5 MHz. The expected answer is 54.0 MHz, suggesting a misunderstanding of the problem's requirements. Participants emphasize the need for clarity regarding the role of heterodyning in frequency reception. The consensus is that receivers should typically be tuned to the same frequency as the transmitters unless additional modulation or frequency mixing is involved.

PREREQUISITES
  • Understanding of radio frequency transmission and reception
  • Basic knowledge of heterodyning in signal processing
  • Familiarity with frequency modulation concepts
  • Experience with circuit setup for RF communications
NEXT STEPS
  • Research the principles of heterodyning in radio communications
  • Learn about frequency mixing and its applications in RF systems
  • Explore tuning techniques for receivers in RF circuits
  • Study the effects of modulation types on frequency reception
USEFUL FOR

Radio frequency engineers, electronics students, and hobbyists involved in RF communication projects will benefit from this discussion.

Homework Statement



I need to calculate the frequency which the receivers should be tuned to too receive one another frequency. Both are transmitting at a frequency of 17.5 MHz. I know the answer should be 54.0MHz.

Homework Equations



Unsure

The Attempt at a Solution



Unsure of how to find the common frequency, I know your suppose to show how you attempted the question but am unsure how to even start. If someone could offer me a formula to start. I'm sure its an easy question, I am a bit stumped tho. Thanks

When I set up a circuit, I tune the receiver to the frequency the transmitter is tuned to (modulo possible offsets due to emission type). Perhaps there is some confusion in the statement of the problem.

Welcome to the PF. I agree with tms about not understanding your problem statement. If you have two transmitters at 17.5MHz, why would the receiver not be tuned to 17.5MHz as well? Is there some heterodyning part to the question perhaps?
