【 Abstract 】 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]

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]

Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]

As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]

To ensure the success of China's TD-SCDMA network commercialization, operators and equipment suppliers need to conduct a large number of tests on networked equipment, among which RF testing is...[Details]

Today, as network technology becomes more and more popular, industrial field instruments, data acquisition and control equipment are becoming more and more networked, and the combination of industr...[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]

Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]

Chapter 1 Proposal Endless salespeople interrupt your normal work schedule; Employees leave their work stations without permission during working hours; Unauthorized persons ente...[Details]

To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]

Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]

According to In-Stat/MDR, the number of mobile phones with Bluetooth capabilities will reach at least 300 million by 2005. One of the clear evidences of the increasing adoption of Bluetooth is that...[Details]

introduction Every friend who has been in contact with PC since the 286 era must have deeply experienced the convenience brought to our lives and work by the leaps and bounds of comput...[Details]

Abstract: Online dynamic signature authentication is increasingly used in various fields, especially in banking and financial systems and personal identification. As the basis of online signa...[Details]

1 Introduction Economic development has prompted people to continuously improve their security awareness. When traditional local analog monitoring methods gradually fail to meet the needs of l...[Details]
