How a CPU is made? [HD Graphics]
07 January 2026
Hello everyone, I am Rose. Welcome back to the new post today. The CPU, sometimes known as a "microprocessor," is the heart of modern computers. The specs and frequencies of the CPU are frequently regarded as crucial indicators of a computer's performance in PCs.
Introduction to Types of Oscillator Circuits
14 January 2026
The oscillator operates on the theory of the oscillation and it is a mechanical or electronic unit. The periodic difference between the two items is dependent on the variations in the electricity. The oscillations are used in the watches, clocks, metal detectors and in many other applications use the oscillators.

Basic Understanding of Attenuators
15 September 2020
An attenuator is used to introduce a predetermined attenuation within a specified frequency range. It is generally indicated by the decibel of the attenuation introduced and the ohm of its characteristic impedance.
What are Laser Diodes?
20 October 2025
Laser diodes include single heterojunction (SH), double heterojunction (DH), and quantum well (QW) laser diodes. The quantum well laser diode has the advantages of low threshold current and high output power, which is the mainstream product in the market. Compared with optical maser, laser diodes have the advantages of high efficiency, small size, and long life, but their output power is small (generally less than 2mW), linearity and monochromaticity are poor, limiting their applications in cable television systems for not able to transmit multi-channel, high-performance analog signals. In the feedback module of the bidirectional optical receiver, the uplink transmission generally uses a quantum well laser diode as a light source.
Working Principle and Application of Infrared Sensors
27 October 2025
The infrared sensor is a sensor used to detect infrared radiation. It mainly has 6 performance parameters including voltage response, response wavelength range, noise equivalent power(NEP), detectivity, specific detectivity, and time constant. There are generally 2 types of infrared sensors, thermal sensors, and photonic sensors. The 2 types have specific working principles but they're both based on the basic law of infrared radiation. And according to the application functions and places, infrared sensors are mainly used in radiation and spectrum measurement, search and track systems, and thermal imaging systems.
Solid-state Drive (SSD): Classification and Architecture
22 May 2021
A solid-state drive (SSD) is a hard drive made of solid-state electronic memory chip arrays. SSD is composed of a control unit and storage unit (FLASH chip, DRAM chip). Solid-state drives are widely used in many fields such as military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical treatment, aviation, navigation equipment, and so on.
DIP Switch: Introduction and Classification
20 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.
What are the Applications of Filters?
17 January 2026
Filtering is a basic and important technique in signal processing. Using filtering techniques, the desired signal can be extracted from various signals and unwanted interference signals can be filtered out. A filter is an important component in the frequency domain analysis of a signal.
Analysis of Semiconductor Wafers
22 October 2025
The wafer is the basic raw material for manufacturing semiconductor devices. Various circuit element structures can be fabricated on silicon wafers, thereby becoming integrated circuit products with specific electrical functions.
Introduction to the Types of Monitor Cables
01 April 2024
At present, the common PC monitor cables mainly include HDMI cable, DP cable, DVI cable, and VGA cable. Monitor cable performance ranking: DP>HDMI>DVI>VGA. VGA is an analog signal. DVI, HDMI, DP are digital signals, which are the current mainstream.
