Suitcase fusion 6 /usr/bin/corecli6/6/2023 ![]() In the case of complex or IQ sampling, you really get two component values (1 I or real or "in-phase" component plus 1 Q or imaginary or quadrature component) per complex or IQ sample time, so you might be able to properly sample a signal with a higher bandwidth up to almost the full sample rate. The criteria for proper (lossless) sampling requires that the total bandwidth of the signal being sampled be below half the sample rate. ![]() $$I = h_)$ĭepending on the application, information in $A$ (the envelope) or in $\phi(n)$ (the phase) is used. Then in order to obtain the I and Q components from $s_r$ you can apply the following just like the analog case: Which is a bandpass, modulated, narrow band signal where the components $I$ and $Q$ are the lowpass baseband in-phase and quadrature-phase components respectively. ![]() Assume that signal that comes to you through your antenna is:
