TET10-14 electrical components refer to integrated circuits that integrate analog circuits composed of capacitors, resistors, transistors, etc., to process analog signals. There are many analog integrated circuits, such as operational amplifiers, analog multipliers, phase-locked loops, and power management chips. The main constituent circuits of analog integrated circuits include: amplifiers, filters, feedback circuits, reference source circuits, switched-capacitor circuits, etc. Analog integrated circuit design is mainly obtained through manual circuit debugging and simulation by experienced designers, whereas corresponding digital integrated circuit design is mostly automatically synthesized under the control of EDA software using hardware description languages. Integrated circuits can be divided into two major categories based on their function and structure: digital IC and analog IC. Digital IC are used to generate, amplify, and process various digital signals (signals that change discretely in time and amplitude). Analog IC are circuits used to generate, amplify, and process various analog signals (signals whose amplitude changes continuously with time); they are one of the core technologies of microelectronics, capable of acquiring, amplifying, comparing, converting, and modulating analog quantities such as voltage or current.

TET10-14 electrical component principles

Electrodynamic loudspeakers, also known as moving-coil loudspeakers, are electro-acoustic transducers based on the electrodynamic principle. They are the most widely used loudspeakers, primarily for three reasons: 1. Electrodynamic loudspeakers have a simple structure and are easy to manufacture; they do not require much space, resulting in low costs and widespread adoption. 2. These loudspeakers can achieve excellent performance, obtaining a uniform frequency response in the mid-frequency range. 3. These loudspeakers are constantly being improved; decades of loudspeaker development history reflect continuous improvements in design, craftsmanship, and materials, as well as performance keeping pace with the times. Electrodynamic loudspeakers are mostly conical or dome-shaped; the structure of a conical loudspeaker can be divided into three parts: 1. The vibration system includes the diaphragm, voice coil, centering spider, dust cap, etc. 2. The magnetic circuit system includes the upper pole plate, pole piece, lower pole plate, magnet, etc. 3. The auxiliary system includes the basket, surround, terminal board, and phase plug. According to Faraday's law, when a current-carrying conductor passes through a magnetic field, it experiences an electromagnetic force; its direction conforms to Fleming's left-hand rule, with the force perpendicular to both the current and the magnetic field directions. The magnitude of the force is proportional to the current, the length of the conductor, and the magnetic flux density. When an alternating audio current is input to the voice coil, the voice coil experiences an alternating driving force that produces alternating motion, driving the paper cone to vibrate and repeatedly push air to produce sound.

When a high-frequency current flows through a conductor, an electric field and a magnetic field are generated in the surrounding space. Based on the spatial distribution characteristics of the electromagnetic field, it can be divided into the near field, intermediate field, and far field. Let R be the distance from a point in space to the conductor; the region where R ﹤﹤ λ/2π is called the near field, where the electromagnetic field is closely linked to the current and voltage in the conductor. The region where R﹥﹥λ/2π is called the far field, where the electromagnetic field can leave the conductor and propagate through space; its changes lag behind the current and voltage on the conductor by a certain period, and the propagated electromagnetic waves no longer have a direct connection with the current and voltage on the wire. The electromagnetic field in this region is called the radiation field. It must be pointed out that when the length of the wire L is much smaller than the wavelength λ, radiation is very weak; when the length of the wire L increases to be comparable to the wavelength, the current on the wire increases significantly, thereby forming stronger radiation. Transmitting antennas utilize this property of the radiation field, allowing transmitted signals to radiate fully into space after passing through the transmitting antenna. How can a conductor become an effective radiating system? Here we first analyze the situation on transmission lines. On parallel two-wire transmission lines, to ensure only energy transmission without radiation, it is necessary to guarantee symmetrical structure of the two lines, with currents at corresponding points on the lines equal in magnitude and opposite in direction, and the distance between the two lines<π. To effectively radiate the electromagnetic field, this symmetry of the transmission line must be broken; methods such as separating the two conductors at a certain angle or removing one side can destroy the conductor symmetry and produce radiation. By separating the open-ended transmission line or the conductor at a distance of π/4 from the terminal in a straight line, the current on the terminal conductor becomes in-phase rather than anti-phase, causing the radiation fields of this conductor segment at spatial points to superimpose in phase, constituting an effective radiation system. This is the simplest and most basic unit antenna, called a half-wave dipole antenna, with a characteristic impedance of 81Ω. After electromagnetic waves are radiated from the transmitting antenna, they propagate in all directions. If a symmetric dipole is placed in the direction of electromagnetic wave propagation, an induced electromotive force will be generated on the antenna dipole under the action of the electromagnetic wave. If the antenna is connected to receiving equipment at this time, a high-frequency current will be generated at the input end of the receiving equipment. Thus, the antenna acts as a receiver, converting electromagnetic waves into high-frequency current; in other words, the antenna serves as a receiving antenna. The quality of reception depends not only on the strength of the radio waves but also on the directionality of the antenna and the matching between the half-wave symmetric dipole and the receiving equipment.

TET10-14 electrical component classification

Fiber optic connectors can be divided into common single-mode and multimode connectors for silica-based fibers based on the transmission medium, as well as other fiber optic connectors using plastic etc. as the transmission medium. Based on the connector structure, they can be classified into: FC, SC, ST, LC, D12, DIN, MU, MT, and various other forms. Among them, ST connectors are typically used at cabling equipment ends, such as fiber patch panels and fiber modules; while SC and MT connectors are typically used at network equipment ends. Based on the fiber end-face shape, they are classified into FC, PC (including SPC or UPC), and APC; based on the number of fiber cores, they are divided into single-core and multi-core (such as MT-RJ). Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them based on the different structures of the fiber optic connectors.
