DIP Switch: Introduction and Classification20 January 2021
DIP switch is an address switch used for operation control, using the principle of 0/1 binary coding. It is a miniature switch that can be toggled by hand. Dip switches are widely used in data processing, communication, remote control and anti-theft automatic alarm systems and other products that require manual programming.
An Overview of Development Board24 August 2021
The development board is a circuit board used for embedded system development. Development boards are generally customized by embedded system developers according to development needs.
LED Driver: Function, Types, and Application01 September 2020
LED Driver refers to the power adjustment electronic device that drives LED light or LED module components work normally. Due to the conduction characteristics of the LED PN junction, the voltage and current range of the power supply it can adapt to is very narrow, and a slight deviation may not be able to light the LED, or the luminous efficiency will be seriously reduced, or the service life may be shortened or the chip may be burned.
What is a High-pass Filter?10 March 2021
A high-pass filter is a combination device of capacitors, inductances, and resistors that allow signal components above a certain frequency to pass, while greatly suppressing signal components below that frequency. The high-pass filter only attenuates the frequency components below a given frequency, and allows the frequency components above the cutoff frequency to pass, and there is no phase shift filtering process. Mainly used to eliminate low-frequency noise, also called low-cut filter.
Ceramic Capacitor Failure Mode and Mechanism Analysis21 May 2022
Hello, this is Candy. A ceramic capacitor is a fixed-value capacitor in which the dielectric is made of ceramic material. It's made up of two or more alternating ceramic layers and a metal electrode layer. The electrical behavior and thus applications of ceramic material are determined by its composition. But when it comes to ceramic capacitors failing, what is the cause of this phenomenon? What's the pattern? This article will introduce you in detail.
Strain Gauges: Structure, Working Principle and Common Types16 December 2020
Strain gauge is a device that changes resistance with force; it converts physical quantities such as force, pressure, tension, and weight into changes in resistance to measure these physical quantities. When an external force acts on a fixed object, stress and strain are generated. The reaction force (external force) generated inside the object is the stress, and the displacement and deformation generated are the strain.
Graphics Card Explained: Classification, Working and Structure27 May 2021
A Graphics card (Video card, Display card, Video adapter) is one of the basic components of personal computers. It converts the display information required by the computer system to drive the display, which is an important component that connects the monitor and the PC motherboard, and is one of the important equipment of "human-machine". Its built-in parallel computing capability is also used for deep learning and other operations.
Linear Induction Motor: Working Principle, Characteristics, and Applications02 March 2021
LIM stands for Linear Induction Motor, and it is an improved version of the rotary induction motor that produces linear translational motion instead of rotating motion. Other than rotating torque, this device generates linear movement and force. By cutting a radically shaped cut in the revolving induction and thus leveling the section, the design and functionality of the linear induction motor can be demonstrated in the diagram below.
Introduction to Ultrasonic Transducer: Working Principle, Types and Applications25 February 2021
One type of sound-related transducer is the ultrasonic transducer. The electrical signals are transmitted to the target by these transducers and after the signal reaches the object, it returns to the transducer. This transducer tests the distance of the object in this method, not the amplitude of the signal. For the calculation of a few parameters, these transducers use ultrasonic waves.
Analog Switch: Types and Application25 March 2021
The analog switch is mainly to complete the signal switching function in the signal chain. The switching mode of the MOS tube is adopted to realize the switching off or on of the signal link.
An Overview of Isolation Transformers17 September 2020
An isolation transformer is a transformer in which the input and output windings are electrically isolated. The isolation transformer is to isolate the current of the primary winding and the secondary winding respectively.
What is LCD? Working and Types02 April 2021
LCD is a liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
