I am studying the principle of filters recently. Regarding the S parameter S21, I would like to ask when S21 is used to indicate insertion loss and when it is used to indicate transmission coefficient...
I want to share files under wince5.0 and then access the shared folder on the PC, so I added the following components: File Server File Server Customizable UI Windows Networking API/Redirector (SMB/CI...
The set value is known, the sampled measurement value of a certain control object at the current moment is known, and the deviation at the current moment can be obtained, but how to obtain the measure...
1. When debugging a program in c2000, if MP/MC=1, is the interrupt vector placed in the FLASH starting at address 0, or in the off-chip RAM? 2. What does the value 40 mean when there is "-stack 40" at...
430 microcontrollers generally have an internal information area to save some data that requires EEPROM to save. I did not receive relevant information in the forum, so I borrowed the information on t...
