Computer switching power supply is a capacitor input circuit, and the phase difference between its current and voltage will cause the loss of switching power. In this case, a PFC circuit is required to improve the power factor. There are currently two types of PFC, one is passive PFC (also called passive PFC) and active PFC (also called active PFC).
I am a beginner and just started to learn msp430. I have a launchpad and want to use it to measure the external temperature and display it on LCD. I can't find any ideas at the beginning. First of all

I don't know how to do it, why can't I just upload the picture? ? Let's get back to the topic: This is the drawing that the customer provided us to modify for making an 11-key remote control. I don't
Error vector magnitude (EVM) measurements can help engineers gain insight into the performance of digital communication transmitters and receivers. For digitally modulated signals, any signal imperfec
I know that the I/O interface addressing methods are divided into memory mapping method and independent addressing method. Is this only determined by hardware? For example, the 8086 series uses an ind
