Analog signal is a signal in which an information parameter appears to be continuous within a given range. Or, in a continuous time interval, the feature quantity representing the information may be p

Cat 7 network cables are a Class F standard twisted pair cable introduced after the Category 6 network cable. They are mainly used in 10 Gigabit Ethernet networks. Generally, they are compared in data

the wiring system materials usually use cable and fiber optic cable as the transmission medium. The types of cables are mainly divided into shielded twisted pair and unshielded twisted pair. The fiber

USB PD-based interface based on USB Type-C interface is one of the most important work results of USB-IF industry association in the last two years, including USB-IF member units Intel, Apple, Google,

VGA to HDMI converter is the most frequently used type in the converter field. HDMI digital signal and VGA analog signal are more common in life. VGA to HDMI interface converter can support video HDMI

VGA3+4 cable and VGA3+6 cable are all specifications of video cable. In VGA cable 3+4 type, 3 means three color wires, also 3 coaxial core wires, 4 means four color wires, and also 4 Wire. The VGA cab

Fiber optical cable is used widely in our life, so how to identify the good fiber optical cable is important. The quality of fiber optical cable can be roughly identified from the following aspects:

Today's HDMI interface not only can meet the current high-definition 1080P resolution, but also supports advanced digital audio formats such as DVD Audio, and can support eight-channel 96kHz and flat-

How to realize data transmission between devices with different interfaces of HDMI and VGA. At this time, we need an HDMI and VGA converter for data conversion to achieve data transmission between HDM

The Cat6 network cables are the most important part of our data center. It is an important part, so the requirements are very high. Flame retardant materials are gradually required in the industry. In

We all know that DVI (Digital Visual Interface) is a digital computer interface.Under normal circumstances, the general DVI cable can only effectively transmit signals about 5 meters, and the attenuat

Compared with USB3.0, the most direct change of USB3.1 is that the speed can reach 10Gbps. To achieve this speed, the first thing to solve is the problem of shielding. Look carefully at all versions o
