What is IQ data signal processing?

Quadrature signals, also called IQ signals, IQ data or IQ samples, are often used in RF applications. They form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis.

How are IQ signals generated?

I/Q signaling refers to the use of two sinusoids that have the same frequency and a relative phase shift of 90°. Amplitude, phase, and frequency modulation can be performed by summing amplitude-modulated I/Q signals. Quadrature modulation refers to modulation that involves I/Q signals.
