I have explained the basics of #UART communication in this video. UART stands for Universal Asynchronous Receiver/Transmitter. It is used in #microcontrollers and FPGAs. I have also covered an explanation of the baud rate, UART frame structure, and parity bit. Comment down your answers to the question. LIKE and SHARE the video. SUBSCRIBE to the channel!

The receiver should sample the signal in its middle (not on the edge). This is because real life electronics aren't perfect, and there may be latency or voltage jumps here and there; so for example a transmitter's voltage level can go from LOW to HIGH, but if it lags by just a few microseconds after the designated time for leading edge arrives, the receiver will actually still see a LOW level signal, which is a mistake. Thus the sampling should be done in the middle.
Data must be sampled at the middle of the pulse to avoid wrong sampling due to practical time mismatches between Tx n Rx. I Would like know if there exists other possibilities too?
According to me the signal should be sampled at the edge i.e when transition takes place according to design we can have positive or negative edge detection.
