1. I recently encountered this problem when adjusting the board: the board functions normally when the emulator is plugged in and running online, but some functions of the board are abnormal when it i...
1. When transferring data from one clock domain to another, a synchronizer made of two flipflops is used in the middle, but the data actually received by the destination may be wrong. For example, the...
We often come into contact with crystal triodes and are familiar with their use. Relatively speaking, we are a little unfamiliar with crystal field effect tubes. However, due to the unique advantages ...
When negotiating LCP in the PPP protocol, what specific options are negotiated? I have the source code for PPP-2.4.1-10 and I don't know where to find which configuration options are negotiated. In op...
It restarts for no reason (without any prompts), sometimes it shuts down automatically and won't turn on. I have to unplug the power cord, press the power button twice, and then plug the power cord in...
1. High frequency resistor
The most common circuit element in low-frequency electronics is the resistor, which is used to reduce voltage by converting some electrical energy into heat. The high-freque...
