Is IQ data in frequency domain?
The IQ data can be in the time domain (time vs amplitude+phase) or, usually post processing with a transform be, in the frequency domain (frequency vs amplitude+phase).
What does IQ stand for in RF?
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.
What is IQ sampling?
IQ sampling is the form of sampling that an SDR performs, as well as many digital receivers (and transmitters). It's a slightly more complex version of regular digital sampling (pun intended), so we will take it slow and with some practice the concept is sure to click!
What is SDR IQ?
The SDR-IQ™ is the smallest SDR with RF DSP™ that samples the whole HF band at once and performs the initial filtering at a 67 MHz sample rate with 23 bit accuracy.
