Latches, Flip-Flops, Registers and Buffers
15 February 2022
Hello everyone, I am Rose. Today I will show you the difference between latch, flip-flop, buffer and register.
How Many Types of Inverters are There?
28 March 2022
Hello everyone, I am Rose. Today I want to introduce types of inverter to you. There are totally 17 types in this article. Let's see what are they?
Introduction to Synchronous Counter and Asynchronous Counter
31 March 2025
The counter is mainly composed of flip-flops. According to the flip order of flip-flops, the counter can be divided into synchronous and asynchronous.
Types, Working, and Selection of DC Motor
27 March 2025
A direct current motor (DC motor) is an electric motor that operates on direct current. The operation of an electric motor is based on basic electromagnetism. When a current-carrying conductor is put in an external magnetic field, it will feel a force that is equal to the current in the conductor and the frequency of the external magnetic field.
Resistor Symbols: From Circuit Diagrams to PCB Design
06 June 2026
This comprehensive guide explores resistor symbols used in electronic circuit diagrams, covering the two main international standards: IEC (rectangle symbol) and ANSI (zig-zag symbol). The article explains how to read and interpret these symbols in schematics, distinguishing between fixed and variable resistors, and detailing specialized types like thermistors, LDRs, and varistors. It provides practical guidance for locating resistor symbols in popular EDA software (KiCad and Eagle) and includes a downloadable reference chart. The guide serves as an essential resource for electronics enthusiasts, students, and professionals who need to understand the universal language of electronic schematic symbols for circuit analysis, design, and troubleshooting.
What is FIR Filter?
24 September 2020
FIR (Finite Impulse Response) filter is a finite-length unit impulse response filter, also known as a non-recursive filter, which is the most basic element in a digital signal processing system. It can guarantee arbitrary amplitude-frequency characteristics while having strict linear phase-frequency characteristics, and its unit sampling response is finite, so the filter is a stable system.
Introduction to Types of Diodes
20 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.
Detailed Introduction of the Chip Design Process
21 December 2021
This article outlines the design process of the chip, and mainly introduces the following aspects: 1. The concept of the chip is explained. 2. Classification of chips. 3. The design process of the chip.
What is a Gyroscope Sensor?
11 September 2020
A gyroscope is a device used to sense and maintain direction, designed based on the theory of indestructible angular momentum. The gyroscope sensor is a simple and easy-to-use positioning and control system based on free space movement and gestures.
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.
How Electric Fuses Work: Types, Ratings, and Selection Guide
14 July 2026
This guide walks through how a fuse actually interrupts a fault, the difference between fast and slow elements, the main fuse families and where each one belongs, the ratings that genuinely matter, and a repeatable method for choosing a fuse for your own circuit. It closes with the mistakes that most often cause either nuisance opening or unsafe under-protection, a clear comparison with circuit breakers, and a frequently asked questions section.
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.
