What is Electronic Ballast?
28 September 2020
Electronic Ballast is a kind of ballast, which uses electronic technology to drive the electric light source to produce the required lighting. Corresponding to it is the inductive ballast. More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and people can even integrate electronic ballasts with lamps.
How a CPU is made? [HD Graphics]
19 January 2022
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 EPROM and EEPROM
14 August 2020
EPROM (Erasable Programmable Read-Only Memory) is a kind of ROM memory with erasable function and can be reprogrammed after erasing. Before writing, the contents inside must be irradiated with ultraviolet rays on the transparent window on its IC card to clear it. EEPROM (Electrically Erasable Programmable Read-Only Memory), a memory chip that does not lose data after power failure. EEPROM can erase the existing information and reprogram it on the computer or special equipment.
Introduction to Pi Filter
19 February 2021
A Pi filter is a type of filter with a two-port, three-terminal block consisting of three elements with two terminals in each element: the first element is connected to the GND terminal via i/p, the second terminals are connected to the terminals from i/p to o/p and the third element is connected to the terminals from o/p to GND. The circuit model is going to be like a 'Pi' symbol. Capacitors and one inductor are the elements used in the circuit.
Introduction to TVS Diodes
07 August 2020
TVS diodes (Transient voltage suppression diodes), also called clamp diodes, are electronic parts for protection, which can protect electrical equipment from voltage spikes introduced by wires. It is a high-performance circuit protection device commonly used internationally.
What is a Cascode Amplifier?
27 March 2025
An analog circuit's output is increased by using a cascode amplifier. The use of cascode is a common approach that can be extended to both transistor and vacuum tube applications. In the year 1939, the tern cascode was included in an article written by Roger Wayne Hickman and Frederick Vinton Hunt.
DVI Connector: Types, Advantages, Distiguishment And Development
18 November 2020
A DVI connector, that is, digital video interface connector, is an interface standard launched in 1999 by the DDWG (Digital Display Working Group) formed by Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies.
The History of Thermometers
13 January 2022
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.
Bridge Rectifier: Functions, Circuits and Applications
03 November 2020
Bridge rectifiers are the most commonly used circuits for rectifying AC to DC using the single conductance of a diode. A bridge rectifier consists of four rectifier silicon chips connected by a bridge and encapsulated in insulating plastic. There is a zinc metal shell over an insulating layer to enhance heat dissipation in a high power bridge rectifier.
