What is IQ demodulator?

I/Q demodulation is a common and useful RF signal processing technique used in charged-particle accelerators.

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 I and Q in IQ demodulator?

In other words, I/Q demodulation is essentially translation: we are translating from a magnitude-plus-phase system (used by a typical baseband waveform) to a Cartesian system in which the I component is plotted on the x-axis and the Q component is plotted on the y-axis.

What's your IQ about quadrature signals?

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.
