| Feb 5, 2017 at 6:38 | comment | added | Chris Stratton | @hotpaw2 it's true that the sample rate isn't over 2x the bandwidth, but the samples per unit of time still must be - you just take two at a time half as frequently. That may ease implementation somewhat at the edge of what a given technology can handle, in the sense that may be easier than having two ADCs take turns on the same signal. | |
| Feb 5, 2017 at 6:28 | comment | added | hotpaw2 | -1 : IQ sampling does not require the sample rate to be 2X or greater than the bandwidth. That's because complex or quadrature samples can represent both positive and "negative" frequency spectra, unlike single channel ADCs. | |
