Clock circuit selection principles 1. When multiple clock signals of different frequencies are required in the system, programmable clock chips are preferred; 2. When a single clock signal is used, a ...
Last time we released spy photos of the Wolverine development board, it has now been confirmed that it is indeed the official development board of Wolverine.Link: https://bbs.eeworld.com.cn/thread-321...
I am honored to have the opportunity to participate in the trial event of the EdgeBoard edge AI computing box held by Mir Electronics . This evaluation will first conduct a simple unboxing of the deve...
x1 x0 --||--|-|\|----y1--| | | y1 | | --||--|------------| I am very confused. After X1 is powered on, there will be a pulse, right? Then it says that Y1 is connected. But that is not right. X0 will r...
Using lpc2478 and keil arm, I encountered the following problems:
Modify the stack initialization program in the startup file: the following program aims to put the stack in the processor's internal R...
1 Introduction
The multifunctional monitor is a commonly used clinical medical device. It can display the patient's electrocardiogram (ECG), respiration (RESP), blood oxygen saturation (SP...[Details]
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[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]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[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]
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]
This article first briefly introduces the working principles of current mode and voltage mode and their respective advantages and disadvantages; then discusses the ideal voltage mode using output c...[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]
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 pres...[Details]
In a Class D audio power amplifier, the preamplifier is a relatively important module. It is located at the front of the entire topology and completes the processing of the input signal source,...[Details]
IPTV (Internet Protocol TV or Interactive Personal TV), also known as interactive network television, is a new technology that uses broadband network infrastructure, takes home televisions or comp...[Details]
Introduction
High voltage power supply is an indispensable part of nuclear radiation detection instrument, which supplies high voltage to nuclear radiation detection devices (such as prop...[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]
