What are Resonators?07 January 2026
A resonator is an electronic component that can generate a resonant frequency. It has the characteristics of stability and good anti-interference performance. Like the low-frequency circuit, the resonator is also the basic component of the radio frequency circuit. It is widely used in filters, oscillators, frequency meters and adjustable In circuits such as amplifiers. The commonly used RF/MW resonators are basically transmission line resonators.
Basic Understanding of Attenuators15 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.
Latches, Flip-Flops, Registers and Buffers15 February 2022
Hello everyone, I am Rose. Today I will show you the difference between latch, flip-flop, buffer and register.
The History of Thermometers09 January 2026
Hello everyone, I am Rose. Today I will introduce you thermometers. Thermometers are tools that can accurately judge and measure temperature and are divided into pointer thermometers and digital thermometers. According to the difference of the purpose of use, a variety of thermometers have been designed and manufactured.
Rheostat Basics: Types, Principle and Functions25 December 2025
A rheostat is a device that can adjust the size of the resistance and can be connected to the circuit to adjust the size of the current. A general rheostat is composed of a wire with a larger resistance and a device that can change the contact point to adjust the effective length of the resistance wire. Rheostat can limit the current and protect the circuit, and change the voltage distribution in the circuit.

Introduction to the Types of Monitor Cables01 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.
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.
Solid-state Drive (SSD): Classification and Architecture22 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.
Introduction to Types of Oscillator Circuits14 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.
Working Principle and Application of Infrared Sensors27 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.
Introduction to Types of Diodes20 October 2025
According to different purposes, diodes can be divided into rectifier diodes, detection diodes, Zener diodes, varactor diodes, photodiodes, light-emitting diodes, switching diodes, fast recovery diodes, etc.
