RFID technology will be ubiquitous in the future, and there is no doubt about it, because it brings convenience and timeliness to people, which means efficiency and...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[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]
Conventional ECG recorders are one of the main means for doctors to diagnose heart diseases, but they can only record short heartbeats. In many cases, it is difficult to record ECG changes during a...[Details]
1 Introduction
In the current test field, the correlation detection method is increasingly widely used for filtering. Correlation filtering can easily separate a signal of a specific frequency...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pressur...[Details]
Abstract: Based on the research of the communication process between the reader and the RFID tag, combined with the EPC C1G2 protocol and ISO/IEC18000.6 protocol, a digital circuit of RFID tag appl...[Details]

In the future, a complete automobile safety system must fully combine gyroscopes, accelerometers, steering wheel and brake pedal position detectors, and tire speed detection systems to accurately ...[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]
When you hear the word digital TV, you may feel fresh and excited, but when it comes to what digital TV is and what it can bring us, you may still be confused. You must be very eager to understa...[Details]
introduction
Usually, there are many input and output ports in RF systems, and it is expensive to use a multi-port network analyzer to analyze scattering characteristics. Therefore, it is ...[Details]
From the moment AVS video was born, scientists and engineers have been working tirelessly to reduce the size of audio and video bitstreams. Various advanced video compression algorithms have emerge...[Details]
Multi-parameter monitor is an important device in clinical nursing. It can monitor the patient's ECG, blood pressure, blood oxygen saturation, respiratory rate, pulse rate and temperature. At present,...[Details]
