Digital or Analog Signal Inversion

Click For Summary
SUMMARY

The discussion centers on inverting incoming digital or analog signals for transmission via an antenna. Participants suggest using operational amplifiers (opamps) or transistors as potential solutions for signal inversion. Key considerations include the frequency range, amplitude of the input signal, and the method of signal delivery, such as coaxial or twisted pair cables. Additionally, the need for a transmission license is highlighted, emphasizing regulatory compliance in signal broadcasting.

PREREQUISITES
  • Understanding of operational amplifiers (opamps) and their applications
  • Knowledge of transistor circuits and their functionality
  • Familiarity with signal transmission methods (coaxial, twisted pair, fiber optics)
  • Basic principles of signal frequency and amplitude
NEXT STEPS
  • Research operational amplifier inverter configurations and their specifications
  • Explore transistor-based signal inversion techniques
  • Learn about signal transmission standards and licensing requirements
  • Investigate the impact of frequency range on signal inversion methods
USEFUL FOR

Electronics engineers, hobbyists working on signal processing projects, and anyone involved in RF transmission and circuit design.

I would like to take an incoming signal (digital or analog), invert it, and send it to an antenna. What is a simple high-level approach to this?

Would an opamp inverter work for you? Or a simple transistor?

PS
what do you mean simple high level approach?

You need to give us more information so that we can offer suggestions. What is the frequency range and amplitude of your input signal? How is the signal delivered to you (via coax, twisted pair, fiber optics, etc.)?

What power supplies do you have available? Have you built circuits bedore using transistors? Using signal transformers? Using opamps? Is this for school, or for a project you want to build for yourself or for work?

And finally, depending on your answer to the frequency question above, do you have a license to transmit this signal over the air with your antenna?
