Digital Product Detector TV Transmitter Assembly

There are all kinds of pictures in electronic equipment. What can explain how they work is electrical schematic diagram, or circuit diagram for short. There are two kinds of circuit diagrams. One describes how analog electronic circuits work. It uses a variety of graphical symbols to represent resistors, capacitors, switches, transistors and other physical objects, using lines to connect components and unit circuits according to the working principle of the relationship. This kind of diagram has long been called a circuit diagram.

The other describes how digital electronic circuits work. It uses a variety of graphical symbols to represent the door, trigger and various logic components, and uses lines to connect them in a logical relationship. It is used to illustrate the logical relationship between each logical unit and the logical function of the machine. In order to distinguish the circuit diagram from the analog circuit diagram, this kind of diagram is called logic circuit diagram, or logic diagram for short.

In addition to the above two types of diagrams, there are commonly used block diagrams. It uses a box to represent a part of the circuit, it can explain the relationship of each part of the circuit and the working principle of the whole machine concisely. A circuit diagram is like an article, the various units are like sentences, and the components are the words that make up the sentences. So if you want to understand the circuit diagram, you have to start with the words -- components. The purpose, category and method of use of such components as resistors, capacitors, inductors and transistors. This article only restates the various symbols which often appear in the circuit diagram, hoped the beginner is familiar with them, and remembers not to forget.

Ground digital TV transmitter mainly consists of 8 parts: modulator, automatic switching and excitation amplifier unit, final power amplifier unit, main control unit, electric control and distribution unit, switching power supply, passive components, cooling system. All working conditions of terrestrial DTV transmitter are displayed by touch LCD in the main control unit. The main control unit consists of the whole machine detection board, main control board, touch screen and so on. The output and transmitted power are displayed synchronously through the touch LCD on the main control panel.
