What is a Monostable Multivibrator?16 January 2021
A multivibrator is an oscillator that uses deep positive feedback to alternately turn on and off two electronic devices through resistance-capacitance coupling, thereby generating a square wave output by self-excitation. The multivibrator has two different electrical states: the output "high" state and the "low" state. The multivibrator provides stable or quasi-stable state to them according to the type of the multivibrator. One such two-state pulse generator configuration is called a monostable multivibrator.
LVDT - Linear Variable Differential Transformer Basics16 January 2021
LVDT is the abbreviation of linear variable differential transformer, which belongs to linear displacement sensor. It is a movable iron core transformer that consists of a primary coil, two secondary coils, iron core, coil frame, shell and other components.
Vibration Isolator: Types and Applications13 January 2021
A vibration isolator is an elastic element connecting equipment and foundation to reduce and eliminate the vibration force transmitted from the equipment to the foundation and the vibration transmitted from the foundation to the equipment. This article will introduce some of the types of vibration isolators and their applications to you.
Basic Introduction to Memristor12 January 2021
Memristor is a circuit device that expresses the relationship between magnetic flux and electric charge. The memristor has the dimension of resistance, but unlike resistance, the resistance of the memristor is determined by the charge flowing through it.
What is An Optoisolator?09 January 2021
An optoisolator, also called optical coupler, optocoupler, and opto-isolator, is a device that encapsulates the infrared light-emitting device, the infrared light receiving device, and the signal processing circuit in the same tube socket.
What is Regulated Power Supply?08 January 2021
Regulated power supply is an electronic device that can provide stable AC or DC power to the load, including AC regulated power supply and DC regulated power supply.
Microwave Diode: Introduction and Types07 January 2021
Microwave diodes are diodes that work in the microwave frequency band. It is a solid-state microwave device. Microwave band usually refers to the frequency from 300 MHz to 3000 GHz. After the discovery of the point contact diode effect at the end of the 19th century, microwave diodes such as PIN diodes, varactor diodes, and Schottky diode tubes appeared one after another. Microwave diodes have the advantages of small size and high reliability, and are used in microwave oscillation, amplification, frequency conversion, switching, phase shifting and modulation.
SAW Filter: Introduction, Features and Applications30 December 2020
The Surface Acoustic Wave (SAW) filter is a passive band-pass filter made by using the piezoelectric effect and the physical characteristics of surface acoustic wave propagation. Its role is to filter and delay electrical signals. It has the advantages of small size, stable performance, strong overload capacity, low phase distortion, and no need to adjust, so it is used in televisions, video recorders, wireless data transmission systems and other fields.
Shift Register: Classification and Working Principle26 December 2020
The shift register is a sequential logic circuit that can be used to store or transmit data in the form of binary numbers. It loads the input data and then moves or "shifts" it to its output every clock cycle, so it is called a shift register.
EMI Filter: Introduction, Functions and Applications23 December 2020
Electromagnetic interference filter, also known as "EMI filter" is an electronic circuit device used to suppress electromagnetic interference, especially noise in power lines or control signal lines. The EMI filter functions as two low-pass filters: one is to attenuate common mode interference, and the other is to attenuate differential mode interference. It is top choice for electronic equipment design engineers to control conducted electromagnetic interference and radiated electromagnetic interference.
Aluminum Electrolytic Capacitor: Structure and Features19 December 2020
Aluminum electrolytic capacitors are electrolytic capacitors with polarity. They are made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and inserted into a bent aluminum strip as the positive electrode. It also needs to undergo DC voltage treatment to form an oxide film on the positive electrode as a medium, which is suitable for power supply filtering or low-frequency circuits.
What are Tilt Sensors?19 December 2020
Tilt sensors are often used to measure changes in the horizontal angle of the system. The level from the simple bubble level in the past to the current electronic level is the result of the development of automation and electronic measurement technology.
