Adding to Neil's excellent answer: No, that figure is not correct. In quite a few ways. I think you need better literature! First of all: This is totally the opposite of how MIMO works: If you had four parallel transmissions that don't interfere with each other, as your parallel lightning bolts indicate, there'd be no need for MIMO: you'd simply had four ...

The colouring of those data bits is figurative. It's far, far more complicated than that. That diagram is what's known known as a Lie to Children. It's the sort of diagram that would be shown in a presentation to politicians when trying to get them to license spectrum to your organisation. Does each parallel data stream carry some of the data? Yes Is the ...

Space Division Multiplexing sounds like snake-oil, but it's real. It's a way to push several independent channels of data over a shared medium. If you have multiple well-isolated coaxial cables, then you would be right to insist that this was in fact a totally obvious way to move signals, and that there are in fact multiple physical channels available, one ...

Thank you for all your help. Unfortunately neither of the suggestions fixed my problem. On point was indeed the timing. I adjusted the SPI clock-rate to cope with the 50MHz of the ADC. With the adjusted clock-rate I got a proper answer from one ADC. Furthermore I checked the timing constraints with the Oscilloscope and they were all good 1. Also, I tried to ...

Examples? There are 1-Wire, AS-Interface, and others, and this TI application note describes a way of doing it with several possible two-wire connections. And yes, it is used often. 1-Wire pulls the line low for very short periods; the longest is the reset pulse (480┬Ás or more). 1-Wire slaves use the 1 state (which is also the idle state) to charge a small ...

Forgive me for my lack of comprehensive signal processing knowledge, but I'd like to reflect on this interesting analogy. To be cautious, I'd rather use the broad term analogy, than duality or equivalency. Shout-out to Noam Chomsky and Douglas Hofstadter! If a waveform with length L is repeated (overlayed and added) by period R<L, its spectrum will be ...
