In Linux, delay functions are usually used for timing. There is a special delay function called sleep, but the biggest problem with this is that the timing time will increase, and the time is not fixe...
When designing a circuit, special attention should be paid to separating the analog circuit from the digital circuit, and the corresponding grounds should also be separated. Improper grounding can cau...
The formation of battery plates is an important part of the battery production process. The so-called formation refers to the process of charging and discharging the plates, that is, using electrochem...
With the improvement of product performance, PCB is also constantly updated and developed, and the lines are becoming more and more dense. "][size=17px]There are more and more components that need to ...
The circuit shown in the figure is a three-digit tachometer used to measure low frequency signals with a repetitive time interval of 0.235 to 15 seconds. The tachometer has a speed range of 4 to 255 r...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Designers of handheld products such as cell phones, digital cameras, MP3 players and personal digital assistants (PDAs) are continually challenged to deliver more functionality in a smaller form...[Details]
Abstract: This paper introduces the origin and new features of MP4, and introduces the core audio compression technology MPEG-2 AAC (Advanced Audio Coding) based on MP4. Finally, it briefly summari...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communication technology since the advent of digital communications. Many new wir...[Details]
Murphy's Law tells us that "what can go wrong, will go wrong". In the testing or production process of video equipment, problems often occur when we least want them to happen and when it is leas...[Details]
introduction
With the improvement of social automation, human-computer interaction capabilities urgently need a major change, and develop in a direction that is more convenient to use and more...[Details]
Anyone who has owned a laptop computer will have noticed that when running on battery power, their portable device behaves differently than when running on AC mains power—the display dims, the proc...[Details]
Abstract:
QT1101 is a QTouch charge transfer (QT) device, a complete digital controller that can detect signals when approaching or touching up to 10 independent keys. It can be widely used i...[Details]
Siimpel announced that its MEMS-based silicon camera technology, SiimpelFocus SF9x, has been used in Motorola's newly released MING A1600 mobile phone. The MING A1600 is the industry's first mobile...[Details]
At present, ECG monitoring systems that mainly collect, analyze and diagnose ECG signals have been widely used, and have played a great role in the prevention and diagnosis of heart diseases.
