Digital or Analog Signal Inversion

Click For Summary
To invert an incoming signal for transmission via an antenna, a high-level approach involves using components like op-amps or transistors. The discussion emphasizes the need for additional details such as the frequency range, amplitude, and method of signal delivery to provide tailored suggestions. It also highlights the importance of understanding available power supplies and prior experience with circuit building. Furthermore, participants remind that legal considerations, such as licensing for transmission, must be addressed. Overall, a clear understanding of the project requirements is essential for effective guidance.

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?
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
