TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is one of the three major standards for the third generation of mobile communications. It is a communication standard with indepen...[Details]

Digital signal processors have efficient numerical computing capabilities and can provide a good development environment, while programmable logic devices have highly flexible configurability. This...[Details]

Overview Bioelectric signals are very weak, and there is strong interference when detecting them. Therefore, there are many technical difficulties in designing high-quality bioelectric ampli...[Details]

With the development of automatic control technology, the application of precision air pressure generation and control technology is becoming more and more extensive. However, the traditional valve...[Details]

TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]

Third generation (3G) mobile phones offer a variety of features with more functionality. As consumers enjoy the latest and better features of these communication devices, they continue to demand lo...[Details]

In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]

introduction The most common flight state of a fixed-wing aircraft is horizontal flight. If it is allowed to fly at a large angle, the action cannot be maintained all the time. If it is al...[Details]

introduction Video surveillance systems are widely used in industrial, military and civil fields, playing an important role in the security and environmental monitoring of these industries...[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]

Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure 1 shows the bootstrap ...[Details]

Industrial control often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]

Lifting wavelet transform not only has the advantages of traditional wavelet multi-resolution, but also simplifies the operation and is easy to implement in hardware. Therefore, it is widely used in d...[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]

Abstract This paper introduces a wireless radio frequency transmission chip nRF9E5 based on 8051 core. The remote control system of flapping-wing micro-aircraft is made by using this chip. Th...[Details]
