Audio Transformer-Types, Functions and Working05 January 2026
An audio transformer is an electromagnetic system designed to separate an input circuit from an output circuit and produce a signal that passes through it with filtering. A varying electromotive force (voltage) in the secondary winding linked to the other circuit is caused by this changing flux.

The article will tell you How to make an Obstacle Avoiding Robot.
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.
What are the Testing Method and Types of Transistors?21 October 2025
A transistor is a semiconductor device that is commonly used in amplifiers or electronically controlled switches. It’s the basic building block that regulates the operation of computers, cell phones, and all other modern electronic circuits. Due to the fast response time and high accuracy, transistors can be used for a variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators.
Comprehensive Introduction to Snapdragon 88828 June 2021
Snapdragon 888 is the mobile phone processor of Qualcomm Company. On December 1, 2020, at the Snapdragon Technology Summit held in Hawaii, Qualcomm announced the launch of the latest generation of flagship SOC-Qualcomm Snapdragon 888 5G mobile platform and Snapdragon X60 5G baseband.
Power Management Integrated Circuit (PMIC) Guide10 February 2022
Power Management Integrated Circuits (PMIC) is a chip that is responsible for the conversion, distribution, detection and other power management of electrical energy in electronic equipment systems.
An Overview of Crystal Oscillator21 September 2020
The oscillator is an energy conversion device that converts DC power into AC power with a certain frequency, and the circuit formed by it is called an oscillating circuit. Some electronic devices require an AC signal with a highly stable frequency, but the LC oscillator has poor stability and the frequency is easy to drift. A special component-quartz crystal is used in the oscillator, which can generate a highly stable signal. This kind of oscillator using a quartz crystal is called a crystal oscillator.
Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
NOR Flash: Working, Structure and Applications18 November 2021
NOR flash was first developed by Intel in 1988, and after so many years of development, it is widely used in various computers and embedded products. NOR and NAND is the two main types of non-volatile memory in the market today.
Introduction to Centrifugal Switch27 January 2021
On the theory of centrifugal power, a centrifugal switch operates. It's just an electric switch. These switches are specially designed for induction motors in single and split phases. As its operation is identical to that of a centrifugal clutch used in vehicles, the centrifugal switch is generally known as 'clutch'.
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.
