IntroductionHow to Read an Electrical Diagram LessonWhat is a circuit Diagram?Circuit diagram is the basic of engineering research and planning. A schematic layout diagram, which is drawn with the standard symbol of physical electricity, can show the working principle of each component and device relationship, Each electronic component has a symbol. After seeing a few circuit diagrams, you’ll quickly learn how to distinguish the different symbols, and provide planning plan for installing electro ...
Schematic DiagramsCLC П-Filter1. Working Principlea. When the positive pulse is input, C1 is charged first, the charging current is ic1, and meanwhile, reaching the peak voltage of pulse. The inductor L also has a linearly increasing current, and the magnetic energy is stored in L. With the increase of the current, more and more magnetic energy is stored, and the capacitor C2 is charged with voltage through inductor L (the charge current is ic2), the voltage of C2 is basically equal to the volta ...
IntroductionThe heat sink has a thermal conductor that carries heat away from the device into fins that provide a large surface area for the heat to dissipate throughout the rest of the components, thus cooling both the heat sink and processor. Both a heat sink and a radiator require airflow and, therefore, both have fans built in.At present, the main failure form of electronic equipment is thermal failure. According to statistics, 55% failure of electronic equipment is caused by temperature exc ...
IntroductionMany engineers who have not used the switching power supply may have some worry about it, such as the PCB layout, the parameter and type selection of components and so on. In fact, as long as you understand the basic principle, the use of switching power supply design is very convenient.A switch mode power supply usually consists of a controller and an output part. Some controllers integrate MOSFET into the chip, which makes it easier to use and simplify the PCB design, but the flexi ...
IntroductionWith the development of science and technology, electronic products are changing with each passing day. Also the electronic assembly technology is facing challenges.

A short vedio to know something about a/d converter:Electronic Basics: ADC (Analog to Digital Converter) The process of converting analog to digital is called the analog-to-digital converter, and the circuit that completes the conversion is called the A/D converter (abbreviate  ADC). Its function is making the analog signal whose time and amplitude are continuously converted to discrete digital signal whose time and amplitude are also discrete. Fig. 1 The Basic Operation of an A/D ...
