How does the USB female socket transmit digital signals? One end of the USB female socket data cable is connected to a computer standard USB plug (large USB head), and the other end has a T-shaped small USB head. People call the electronic circuits used to transmit, control or transform digital signals as digital circuits. So, what are the characteristics of the digital signal transmitted by the USB female socket?
Feature 1. The USB socket can be used for digital mobile devices to interact with the computer USB port, transfer data, and supply power and smart charging for digital mobile devices;
Feature 2: In electronic equipment, USB sockets usually divide circuits into analog circuits and digital circuits. The former involves analog signals, that is, a continuously changing physical quantity. A series of pulses (voltage) are generated on the resistance R. This is Digital signal;
Feature 3. The USB socket adopts a dedicated intelligent charging management chip for lithium batteries, which can provide fast and intelligent charging for mobile phones, digital cameras, MP3, MP4 and other products through the computer USB port. The double flat pin part can be rotated at will into a parallel or figure eight shape (ie : Rotate into Chinese, American, Japanese, or Australian style pins).
