Clamp Diodes: Principles, Functions, and Applications
27 October 2020
Clamp means jamming the position. In circuit, is means controlling the voltage. Clamp Diode is a kind of diode that is used to limit the potential of a certain point in the circuit, controlling the input voltage to a peak value to a predetermined voltage, without changing the signal. The working principlealso the unidirectional conductivity of the diode.
Basic Introduction to Digital Filter [Video]
23 October 2020
A Digital filter is an algorithm or device composed of a digital multiplier, adder, and delay unit. The function of the digital filter is to perform arithmetic processing on the digital code of the input discrete signal to achieve the purpose of changing the signal spectrum. The method of the digital filter to filter the signal is: use a digital computer to process the digital signal, and the processing is to calculate according to the pre-programmed program.
What is an Encoder?
20 October 2020
An encoder is a device that compiles and converts a signal (such as a bitstream) or data into a signal form that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals.

Power Transformer Basics and Operation Cautions
16 October 2020
A power transformer is a static electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. It is a necessary equipment for power transmission and distribution and power distribution for power users...
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.
Introduction to Step-down Transformers
14 October 2020
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal low voltage output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation not only relates to its own safety and reliable power supply for users, but also directly affects the stability of the power system...
What is an Electromagnetic Relay?
13 October 2020
Electromagnetic relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually a kind of "automatic switch" that uses a smaller current and a lower current to control a larger current and a higher voltage. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
An Overview of Thermal Overload Relays
12 October 2020
Thermal overload relays are protective electrical appliances used for overload protection of motors or other electrical equipment and electrical circuits, The thermal overload relay is mainly used for overload protection of asynchronous motors. After the overload current passes through the thermal element, the bimetallic sheet is heated and bent to push the action mechanism to drive the contact...
Basic Introduction to Power Amplifier
10 October 2020
Power amplifier refers to an amplifier that can generate the maximum power output to drive a certain load (such as a speaker) under a given distortion rate. The power amplifier plays a pivotal role of "organization and coordination" in the entire audio system, and to a certain extent dominates whether the entire system can provide good sound quality output.
What is a Voltage Controlled Oscillator?
08 October 2020
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
How do We Select Automotive Relays?
30 September 2020
A relay is an automatic control device whose output will have saltatory change when the input (electricity, magnetism, sound, light, heat) reaches a certain value. Automotive relays are relays used in automobiles. Such relays have high switching load power, high shock resistance and vibration resistance. Most power supplies in automobiles use 12V, and most of the coil voltages are designed to be 12V...
