Questions relating to the rate at which bits are transmitted over a channel (wired or wireless). Usually specified in bits/s or a multiple of that unit. Related but not the same as baud rate or symbol rate.

Nyquist theorem, seems wrong to me
For Nyquist theorem, for channels without noise the bit rate is:
\$N=2B\log_2(L)\$
N= bit rate, B= bandwidth, L= number of levels
Intuitively I say that it should be:
...

Why a high number of harmonics means a lower bitrate?
I am studying on a book (I'm still at basics) and I haven't understood why a signal with a lower number of harmonics implies a low bit rate. I have this figure:
It clearly shows how a signal with ...

SPI: effective payload throughput per clock tick?
Let's say I'm clocking a SPI bus at 30 MHz.
What payload throughput can I actually expect? 30 Mbps, or less?
(E.g. are high overheads imposed by pauses, control packets, packet headers, packet ...

Wireless Audio Transmitter
I am working on a project that will digitize an audio signal from a standard RCA jack and transmit that signal using Bluetooth to a receiver and then convert it back to an analog signal which I will ...

9bits/signal element, what's the bandwidth?
If I encode 9bits/signal element, what is the minimum required bandwidth of the channel in Hertz?
With the information that 9bits/signal element, is it possible to find its bit rate or any other ...
