What is Sequential Logic?15 October 2020
Sequential logic is an important part of digital logic circuit, which is mainly composed of storage circuit and combinational logic circuit. Sequential logic is also called sequential logic circuit. It is different from other circuits that we are familiar with. Its output state at any time is determined by the input signal and the original state of the circuit at that time, and its state is mainly memorized and represented by the storage circuit.
What is Amplifier?08 November 2025
Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input signal, and is composed of tubes or transistors, power transformers and other electrical components. Used in communication, broadcasting, radar, television, automatic control and other devices.
What is a Fiber Optic Connector?27 October 2025
Fiber optic connector is a detachable (movable) device between optical fibers. It precisely connects the two end faces of the optical fiber so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent.

The Introduction of Oscilloscope Probes11 January 2022
Hello everyone, I am Rose. Welcome to the new post today. The oscilloscope probe is critical to the accuracy and correctness of the measurement results. It is the electronic component that connects the circuit under test to the input of the oscilloscope.
What is an Integrated Circuit (ICs) and Why Integrated Circuit is shortage?23 September 2021
An Integrated Circuit(IC), or we can call it IC, chip, or microchip is a small semiconductor-based electronic device minuscule chip consisting of fabricated transistors, resistors, and capacitors, and other metallic connections required for a complete electrical circuit. In this article, we will discuss it in five aspects.
Arduino Authorized Distributor | UTMEL Electronics22 February 2025
UTMEL, a globally renowned distributor of electronic components, recently announced that it has officially become an authorized distributor of Arduino.
What are Shunts?07 December 2020
A shunt is a measuring element that uses voltage to indicate current. It is made according to the principle of generating voltage at both ends of the resistor when DC current passes through the resistor. It is connected in parallel with the current circuit of measuring instruments to expand its measurement range; or An element on which voltage is measured, thereby indirectly measuring current.
Classification and Working Principle of Ballast Resistor18 November 2020
The ballast resistor is connected between the power source and one or more discharge lamps and is mainly used to limit the current of the lamp to a required value. It may include devices that change the supply voltage or frequency and increase the power factor, which can be used alone or together with the starter to provide the necessary conditions for the lamp to start.
