AD-DC rectification, precision rectification:1. What are the differences between a rectifier bridge, four diode rectification, and op amp rectification?2. After rectification, why is the positive half
In the development of MCU embedded systems, debugging is essential. For some developers who lack expensive debugging equipment, they need to find another way. Therefore, serial port debugging componen
Bare metal systems and RTOS systemsToday's embedded systems are becoming more and more complex. They not only have certain computing requirements, but also require GUI to achieve human-computer intera
We used multiple models of LOTO oscilloscopes, with bandwidths ranging from 20M to 100M , to measure passive and active crystal oscillators . We tested the waveforms of 12M, 15M , 24M, 48M, and 80M cr
