I/Q Data: Plain and Simple


I/Q signals, or I/Q data, are a fundamental element of RF communications systems.

In RF communications systems, I/Q data often represents signals in the time-domain. You may find this video helpful if any of the following apply to you:

  • You want to learn about the basic building blocks of RF communications systems.
  • You want to understand more about I/Q data, quadrature amplitude modulation (QAM), or RF upconverters.
  • You want to find a real-world use for imaginary numbers, besides AC circuit analysis.

NI creates hardware for wireless design and test that you can use to analyze I/Q or produce I/Q data.
