How does the USB socket transmit digital signals? One end of the usb female data cable is connected to a computer standard USB plug (large USB head) and the other end has a T-shaped small USB head. Electronic circuits used to transmit, control, or transform digital signals are referred to as digital circuits. Then, what are the characteristics of the USB digital transmission of the digital signal?

Features 1, the usb female seat can be used for digital mobile devices to connect with the computer USB port, interact and transmit data, and supply power and intelligent charging for digital mobile devices;

Features 2, usb female in the electronic equipment, usually the circuit is divided into analog circuit and digital circuit, the former involves analog signals, that is, the continuously changing physical quantity, a series of pulses (voltage) is generated on the resistor R, which is Digital signal; 

Features 3, usb female seat uses lithium battery special intelligent charging management chip, can provide fast intelligent charging double flat pin part for mobile phone, digital camera, MP3, MP4 and other products through computer USB port, can be rotated into parallel or octagonal type (ie : Rotate into Chinese, American, Japanese, or Australian style).
