What is RF Filter?09 December 2021
Hello, I am Rose Welcome to the new post today. The radio frequency filter is a filter circuit made up of capacitors, inductors, and resistors that is used to filter the signal frequency in communication channels. The filter allows signals that meet a specific frequency to pass while suppressing unwanted frequency signals.
What is a Schmitt Trigger?09 December 2021
Schmitt triggers have two stable states, but unlike general triggers, Schmitt triggers use a potential trigger mode, and their state is maintained by the input signal potential. Schmitt triggers have different threshold voltages for input signals with two different changing directions, negatively decreasing and positively increasing.
What is GND in a Circuit?08 December 2021
In this article, you will learn the classification of GND and its working principle. GND is an abbreviation for the ground. GND represents the ground wire or the 0 wire. This ground is not a real ground, it is a ground assumed for the purpose of application. For the power supply, it is the negative pole of a power supply.
What is Optical Module?08 December 2021
Hello everyone, I am Rose. Today I will introduce optical module to you. A photoelectric and electro-optical conversion optical module is an optoelectronic device. The optical module's transmitting end converts the electrical signal to an optical signal, while the receiving end converts the optical signal back to an electrical signal.
Introduction to BGA Package07 December 2021
BGA (Ball grid array) package is a high-density surface-mount technology. At the bottom of the package, the pins are all spherical and arranged in a grid-like pattern, hence the name BGA.
What are Electromagnetic Waves?07 December 2021
Hello everyone, I am Rose. Today I will introduce Electromagnetic waves to you. Electromagnetic waves are a type of electromagnetic energy.It can be considered the most perfect signal carrier because it can be carried without restriction in open space, as well as through metal transmission lines and controlled freely.
What is Semiconductor Package?06 December 2021
Semiconductor package is the process of assembling integrated circuits into chip final products. Simply put, it is to put the integrated circuit die (Die) produced by the foundry on a substrate that plays a supporting role, lead out the pins, and then fix the package into a whole.
Is Electromagnetic Radiation from Base Stations Terrible?06 December 2021
Hello everyone, I am Rose. Today I will introduce electromagnetic radiation to you. Through this article, I hope that everyone can better understand electromagnetic radiation and protect themselves better.
H-bridge: Working, Circuits and Applications03 December 2021
The H-bridge is a typical DC motor control circuit, named after its resemblance to the letter H. The four triodes form the four vertical legs of the H, and the motor is the horizontal bar in the H.
The Introduction to USB Type-C Pin Signal and PCB Layout03 December 2021
Hello everyone. Welcome to the new post today. USB Type-C is a smaller-volume USB interface standard than Type-A and Type-B. It can be used on a PC (master device) as well as external devices (slave devices, such as mobile phones).
What is SMT (Surface Mount Technology)?02 December 2021
SMT (Surface Mount Technology) refers to the abbreviation of a series of technological processes that are processed on the basis of PCB. SMT is the most popular technology and process in the electronic assembly industry.
