other colors can stimulate these cells to different degrees and generate different color signals. When the three color sensing cells are stimulated to the same extent, they produce white signals. After comprehensive analysis of the visual neural system, these color signals will produce different colors in the visual center of the brain. People with normal colors can distinguish over one hundred different colors. The color of an object is determined by the color of the light reflected after t

Reference: 1. wikipedia The dipole antenna is the simplest and most widely used class of antenna. It consists of identical conductive elements such as metal wires or rods, which is usually bilaterally symmetrical. Each side of the feedline to the transmitter or receiver was connected to one of the conductors. Dipoles is resonant antennas, meaning that the elements serve as resonators, with standing waves of radio current flow ing back and forth between their ends. So the length of the dipole e

Each frame data has the deviation to the location information of the same obstacle. So we first sampled the points that needed to be located. During the sampling process, data loss is encountered, or multiple obstructions are det

With the rapid growth of data, video, and mobile communication services, large-particle businesses surge. Traditional SDH systems cannot meet the demand for rapid growth of large-particle businesses, however, the wavelength division network is the most cost-effective transmission network for bit transmission. It has advantages unmatched by other technologies in large-particle bandwidth transmission solutions. Due to the characteristics of data service

multi-channel signals. Time division multiplexing is suitable for the transmission of digital signals. Because the bit transmission rate of the channel exceeds the data transmission rate of each signal, the channel can be divided into several fragments by time to rotate to multiple signals. Each time slice is occupied by a multiplex signal, in the specified time, many digital signals can be transmitted according to the required transmission, which also realizes the transmission of multiple digi
