Hello everyone: Theschematic diagram is an inverting amplifier. I found that after connecting capacitor C2, there will be a 90-degree phase shift between Vout and Vin.Questions:1. Why does a 90-degree...
I recently encountered a strange problem. The company made a new board. After burning the program, it couldn't run no matter what I did. Even after deleting all parts of the program and leaving only t...
I am doing embedded development under Japanese system. I just arrived at the company and I don't know anything. Does anyone have initial experience using Japanese system? What problems are likely to o...
[size=4]Generally, DSPs are integrated with I2C modules, so that external devices can be easily controlled when connected. I2C is basically used for external control because it is a serial bus. On our...
This is my first time using STM32. I read the introduction and it said that STM32F107 supports USB and 2-way CAN, so I chose it. Now I start to design it, and I found that USB and CAN are shared. I ha...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
