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]

As microcontrollers become less expensive and more powerful, electrical designers are finding it more cost-effective to use multiple small controllers in both single-board and multi-board systems. ...[Details]

Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[Details]

summary Theoretically explains how to set up a PFC boost regulator using a current sensing transformer with the UCC3817 control IC. 1. Schematic The schematic diagram is show...[Details]

A well-designed electronic load is not designed just for use in the lab; it should be carefully designed and built to test actual power systems. This is true for military portable systems, such as ...[Details]

1. Introduction The UCC28051 reference design is a 100W offline AC/DC voltage converter with power factor correction (PFC). This power module design is intended to illustrate how to proper...[Details]

Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]

1. What is fading? In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[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]

1 Introduction Intelligent software agents are software programs that can perform specific tasks for users, have a certain degree of intelligence, can autonomously perform some tasks, and ...[Details]

l Introduction Traditional human-computer communication is achieved through keyboard or mouse. The speed of information exchange is relatively slow, and the operator is required to have certain...[Details]

Abstract: Under high dynamic conditions, combined with GEC's twelve-channel correlator GP2021, this paper discusses the structural design of GPS receivers and the key technologies inv...[Details]

Abstract: In many SCART applications, due to the complex signal switching requirements, dedicated ICs are usually used to implement SCART connections. This will bring cost pressure to single SCART ...[Details]

With the continuous development of the national economy, the application of variable frequency speed regulation devices is becoming more and more extensive. How to break the monopoly of foreign produc...[Details]
