Understanding Computer Memory: From SIMM and DIMM to DDR523 May 2025
DIMM, Dual in-line memory module, is a memory stick that appeared after the launch of Pentium CPU, which provides 64-bit data channels.
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.
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?
Everything You Need to Know about RF Chip05 January 2022
RF chip is one of the most important cores of cell phone terminals. The RF chip is responsible for RF transceiver, frequency synthesis, and power amplification.
Working Principle and Application of Infrared Sensors19 June 2020
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.
Rheostat Basics: Types, Principle and Functions08 December 2020
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.
0 Ohm Resistor Explained10 December 2021
This article mainly introduces the resistance value of 0 ohm resistor, over-current capability, special high rated current 0 ohm resistor and PCB board designed with 0 ohm resistor.
Detailed Explanation of MOSFET12 March 2022
Hello everyone, I am Rose. Today I will introduce MOSFET to you. Metal-Oxide Semiconductor Field Effect Transistor (MOSFET) is a field effect transistor that can be widely used in analog circuits and digital circuits
What are Resonators?09 December 2020
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.
Capacitor Basic: How do Capacitors Work?18 April 2025
