15 February 2022
Hello everyone, I am Rose. Today I will show you the difference between latch, flip-flop, buffer and register.
What is Server and Why does a Server Crash?
14 September 2021
The server provides computing or application services for other clients (such as PCs, smartphones, ATMs, and other terminals or even large equipment such as train systems) in the network.
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.
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.
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?
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.
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.
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.
Ohmic Resistors: Differences, Laws, and Applications
08 June 2026
This article explores the fundamentals of ohmic resistors, which obey Ohm's Law and exhibit a linear voltage-current relationship. It contrasts them with non-ohmic resistors, whose resistance varies with voltage, current, or temperature. Key topics include graphical analysis, practical applications in circuits, and the impact of material choice and temperature. The article also highlights common pitfalls, real-world usage, and tips for selecting the right resistor. Understanding ohmic resistors is essential for effective circuit design, offering predictability, reliability, and simplicity across a wide range of electronic systems, from beginner projects to advanced engineering applications.
