the difference between the upper and lower frequencies in a contiguous set of frequencies

; only bandwidth and SNR are relevant. Cause I think the one from 1 GHz to 1.02 GHz is faster, since it has a higher frequency. But that's plain wrong. It's not based on an understanding of what … . But the more often you change what you're transmitting, the higher the bandwidth. Whether that happens in a channel around 100 MHz or around 72 GHz makes no difference whatsoever. …

No you can't, because the internet depends on you having a method of sending data. For example, the question you've asked here came here somehow, so it's obvious you need to be able to send data. No …

They both define the amount of data you can get through a channel -- the channel bandwidth, together with the SNR, defines the channel capacity $C$, which has the unit of $\frac{\mathrm{bit}}{\mathrm … {s}}$ (which, by the way, is simply $1$ binary decision per second), giving you the maximum amount of information you can get through that: $ C_\mathit{Shannon} = f_\mathrm{bandwidth} \log_2 ( 1 …

help you: each of two potential the UBX per motherboard has a fixed frontend bandwidth of 160 MHz, and thus if you tune them to the same center frequency, you'd still only see. ±80 MHz around that … you should be asking yourself is how much phase continuity and gain consistency you need at the region where the lower UBX's bandwidth gets combined with the upper one's. That will dictate the exactness of phase tracking, the length of the involved filters and thus the feasibility of it all. …

In lack of more background, I can only give a general answer: What you describe is simply an interleaved ADC; that is a technique employed in very high-rate ADCs. And high-rate definitely is more in …

Yes, the length of a filter limits the "frequency-selectiveness". If you remember modern physics, that's mathematically very related to the Heisenberg uncertainty principle: something that is temporal …

$\delta_k0\,\forall k$) nor practically matter (compare: undersampling), we can just sample sufficiently by observing the sum bandwidth. Note that this has very practical effects, for example, when sampling signals that are reflected by moving targets. …

, given that you mix the same signal to these carriers. Indirectly, there might be influences: Bandwidth is proportional to capacity; it's impossible to get 1 GHz bandwidth centered around 433 MHz …
