I would like to share a good document with you by taking advantage of your popularity - Freescale 09FTF. These documents were brought back by EEWORLD from Freescale's FTF event held in Shenzhen at the...
As FPGAs become a viable option for high-performance signal processing circuits in digital communications designs (cellular base stations, satellite communications, and radar), analysis and debugging ...
When debugging the hwcap example in driver studio V3.1, I found that AVStream divides each frame image buffer into several mapping items of 4K Byte in size. Each mapping item describes a continuous ph...
IntroductionNoise must be minimized in precision instrumentation or radio frequency (RF) circuits, but reducing noise presents many challenges due to the nature of these systems. For example, these sy...
A friend of mine was working on a project and found that the PCB parasitic inductance was so severe that it affected the reliability of the circuit. However, the board has been made. Is there any way ...
Before realizing the flashing light, I encountered many problems when installing MDK500. One problem was that the registration machine had problems and could not be cracked, but it was still fixed. An...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
Traditional broadcasting systems generally need to be operated manually at a fixed time, and can only realize one-way broadcasting with few functions. Traditional bell ringing equipment has a singl...[Details]

With the growth of parking demand, the scale of parking lots is becoming larger and larger. A lot of research has been done on intelligent parking lots in China, but most of th...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
Converged processors meet scalability requirements
In current embedded system design, solutions based on MCU, DSP, FPGA and ASIC account for more than 90% of the market share. These solutions ...[Details]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
