There’s a great explanation of phase noise, as well as a specific application note about clock jitter and analog converters. We’ve talked about phase noise in direct digital synthesis a few times.

For many years now, the so-called ‘Blue Pill’ STM32 MCU development board has been a staple in the hobbyist community. Finding its origins as an apparent Maple Mini clone, the diminutiv… ...

We wanted to learn whether the STM32 MCU can provide enough performance. We were not sure if the CPU’s speed would be enough for that rendering scene to be smooth, since as we found out, even screen ...
