STM32F103 UART DMA transmits corrupted data sometimes
I`m using STM32F103CBT6 core with UART via DMA on 9600 baud rate.
The device in idle state transfers data between controller and bill validator unit. In the same time I`m sniffing the data that are ...

Has any design successfully used rolling element bearings to conduct current reliably?
I am curious about using a rolling element bearing (several) to deliver either signals, processing power, or even drive power to a rotating shaft.
As I understand, all bearing manufacturers discuss ...

Why is the insulator missing for one of the transmission lines?
Why is the insulator missing for one of the transmission lines? Apart from the top line (earth) I would assume that all the other lines need an insulator.
It's the same for the next poles. This is in ...

Feeding multiple analog video channels onto a common bus - signal integrity issue?
Consider the following simplified schematic:
The intention here is to have multiple analog video input channels selectively coupled trough an analog switch onto a shared bus (this bus will be on a PCB)...

What's wrong with the tx circuit?
Whenever I connect the power source, the transformer heats up, measures 0v AC and rectifier doesn't measure any voltage in DC.
I feel there are components I need to add to the tx circuit. I'm trying ...

How phase is modulated according to our message signal?
My question: let message signal m(t) be sin(w1t).For frequency modulation (instantaneous phase deviation=phi(t)) d[phi(t)]/dt=kf m(t) so i get that at 90° or π/2 frequency will be max because the ...

Why don't we use the Earth to transmit electricity?
Think about it, instead of transmitting electricity in 2 wires, we could only use one:
Why don't we just do it? I think they do it in three-phase transmission by connecting the neutral phase to the ...

Why the increase of the Spreading Factor (SF) by one, in the LoRa modulation, results in doubling of the transmission time of a symbol (T_symbol)?
Recently, I have been reading about the LoRa modulation and I am curious, why the symbol transmission time (T_symbol) doubles, if the Spreading Factor (SF) is increased by one.
The SF is equal to the ...

Deriving power formulas for transmission lines
I'm trying to derive formulas for active power (\$P_s\$) and reactive power (\$Q_s\$) at the sending end of a transmission line shown below:
Where:
\$E_s\$ and \$E_r\$ are voltage magnitudes
\$X\$ is ...
