Inductance Basis: Definition, Structure and Applications18 April 2022
Hello everyone, I am Rose. Today I will introduce inductance to you. Inductance is a property of a closed loop and a physical quantity. It is a circuit parameter that describes the induced electromotive force effect in this coil or in another coil due to changes in coil current. Inductance is a general term for self-inductance and mutual inductance. A device that provides an inductance is called an inductor.
Filter Circuit: Types, Characteristics and Principles01 December 2021
The rectifier circuit output voltage is a one-way voltage and cannot be used directly on the electronic circuit. Therefore, it is possible to filter the output voltage, eliminate the AC component in the voltage, and use it to the electronic circuit after DC. In the filter circuit, a device that has special impedance characteristics of AC is mainly used, such as a capacitor, inductor. This article will analyze the various forms of filtering circuits.
Introduction to TFT Displays29 August 2020
TFT Display is a thin film transistor type liquid crystal display. TFT liquid crystal is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses. So each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also allows precise control of displaying color gradation, so the color of TFT liquid crystal is truer.
Introduction to AC motor05 March 2021
The motor which uses an electromagnetic induction phänomen to convert the alternative current into mechanical power is called an AC motor. An alternating current drives this motor. Two main components of the AC motors include the stator and the rotor. The stator is the motor's permanent component, and the rotor is the revolving part of the motor. The AC motor can be single or 3-phase.
What Is an Electrical Connector? Types and Selection Checklist14 July 2026
This guide walks through the parts that actually matter, the main connector families and how to tell them apart, the locking methods that keep a mate secure, the role of contact plating, and a practical checklist you can apply when selecting one. It closes with the failure modes worth knowing and a short set of frequently asked questions.
The Ultimate Guide to AI Noise Reduction Translation Earbuds24 September 2026
In today’s connected world, talking to others is very important. You’ve likely seen how global business, travel, and learning need easy chats in different languages. This need keeps growing because of new tech like 5G and edge computing. These make fast and smooth connections possible.
What is a Voltage Controlled Oscillator?09 January 2026
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
Introduction to Bandstop Filter28 January 2021
There are numerous filter types, including high-pass filters, low-pass filters, bandpass filters, and filters for bandstops. The high-pass filter only allows frequencies greater than the cut-off frequency, and the low-pass filter allows frequencies smaller than the cut-off frequencies. A specific band of frequencies will be permitted by the bandpass filter and a band stop filter will reject a specific band of frequencies. An overview of the bandstop filter is discussed in this article.
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.

Dismantling and Analyzing Each Component in the Switching Power Supply16 February 2022
Switch Mode Power Supply (SMPS for short), also known as switching power supply, switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture.
