What is ISP (Image Signal Processor)?15 September 2021
The ISP (Image Signal Processor) is mainly responsible for the photographing part in the system-on-chip (SOC) of the mobile phone.
Working Principles and Applications of Pressure Sensors07 April 2025
A pressure sensor is a device that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to certain rules. The pressure sensor usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
What are the Differences Between Pull up and Pull down Resistors?16 April 2020
Pull up is to clamp an uncertain signal to a high level with a resistor, and the resistor also acts as a current limiter. In the same way, pull down means to clamp the uncertain signal to a low level through a resistor. To pull up is to input current to the device, and the pull-down is to output the current.
Does the Terminal Resistance of the CAN Bus Have to be 120Ω?19 April 2022
Hello everyone, I am Rose. Today I will introduce Controller Area Network（CAN）to you. Knowing the function of terminal resistor will help us better understand causes of waveform instability and other problems in daily work.
What is a Memory Controller?12 August 2020
The memory controller is an important part of the computer system that controls the memory and is responsible for data exchange between the memory and the CPU. The memory controller determines the maximum memory capacity that the computer system can use, the number of memory banks, memory type and speed, memory particle data depth and data width, and other important parameters. The memory controller determines the memory performance of the computer system and therefore has a greater impact on the overall performance of the computer system.
Working Principle and Types of Throttle Position Sensor01 April 2024
The throttle position sensor is also known as a throttle opening sensor or a throttle switch. Its main function is to detect the engine is in an idle condition or a load condition. It is an acceleration and reduction. It is essentially a variable resistor and several switches, mounted on the throttle
What is a Safety Capacitor?08 April 2025
Why do we need a safety capacitor? Because after the safety capacitor fails, it will not cause electric shock and does not endanger personal safety. In industrial, safety capacitors are capacitors that meet safety regulations and have passed the safety test.
Nickel-Cadmium Battery: Construction, Features and Working Principle06 March 2021
A nickel-cadmium battery is a system that generates DC voltage by a chemical reaction between the components. In a nickel-cadmium battery, the redox material serves as the nucleus, with a nickel sheet and a separator surrounding it. The voltage of the nickel-cadmium cell is about 1.2 V. As three or four cells are connected in sequence, the output voltage ranges from 3.6 to 4.8 V.
Basic Introduction to Filter Capacitor05 December 2020
The filter capacitor refers to an energy storage device installed at both ends of the rectifier circuit to reduce the ripple coefficient of AC pulsation and improve the efficient and smooth DC output.
An Overview of LPDDR30 October 2020
LPDDR (Low Power Double Data Rate) SDRAM, a type of DDR SDRAM, also known as mDDR (Mobile DDR SDRAM), is a communication standard developed by the JEDEC Solid State Technology Association for low-power memory. Known for low power consumption and small size, it is specially used for mobile electronic products.
Sensor Basics: Classification, Working Principle and Application02 April 2025
A sensor is a detection device that can sense the measured data and convert it into electrical signals or other required forms of information output according to particular rules, in order to meet the requirements of data transmission, processing, storage, and display, as well as recording and control. Sensors are frequently categorized based on their functioning principle, input data, and application scope. They may be loosely split into three types based on their diverse functioning principles: physical type, chemical type, and biological type.
How do Parking Sensors Work?01 August 2020
The parking sensor also called "parking aid", is mainly composed of ultrasonic sensors, controllers, and displays. It helps the driver "see" the invisible things in the rearview mirror, and inform the driver of the obstacles around the driver by sound or a more intuitive display.
