In the process of using servo drives, we all need to debug the drives. The most critical parameter debugging is PID parameter tuning. Many novices often lack experience in this area and don't know whe
There are many types of antennas in IoT design, the most common ones are ceramic antennas, PCB antennas and IPEX antennas. IPEX antennas can be subdivided into many antennas, so different scenarios ma
Pulse Width Modulation (PWM) is a common method to generate analog voltages from digital devices such as microcontrollers or FPGAs. Most microcontrollers have built-in dedicated PWM generation periphe
First of all, what is a mode? A mode is the solution of Maxwell's equations without an excitation source.T is the abbreviation of transverse, which means "transverse". In the model, it specifically re
