introduction At the beginning of this century, Veit used Einthoven's galvanometer to record the electrical activity of the human pregnant uterus from the body surface for the first time. In 19...[Details]

Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]

With the development of the automobile industry, the complexity and information density of automobile information systems are increasing. Displays are no longer just basic centralized instrument di...[Details]

With the rapid development of computer technology, embedded image systems are widely used in office equipment, manufacturing and process design, medical, monitoring, sanitary equipment, transportat...[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]

Over the past 15 to 20 years, automotive power MOSFETs have evolved from an initial technical topic to a thriving commercial sector. Power MOSFETs were chosen because they can withstand transient ...[Details]

There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows: Oscilloscope pre-stage attenuation c...[Details]

At present, the IEEE802.11 wireless LAN standard is widely used in voice communication, wireless office and other fields, but it is still mainly limited to wireless communication on general platfor...[Details]

Preface In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]

Introduction Wireless operators are driving demand for broadband and data rates by offering enhanced data services to increase average revenue per user (ARPU). The need to provide users with ...[Details]

Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[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]
