◎Electromagnetic Interference (EMI): Any electromagnetic phenomenon that may reduce the performance of a device, equipment or system, or may have adverse effects on organisms or materials. Generally s...
Let me ask you a question:How long does it take to directly call the sin or cos function in 28335 for one calculation?I wrote a simple program in dsp to calculate sin(x) 100 times, then toggle-flip a ...
I have a question. For a ZigBee network, there is a coordinator, two routers and a terminal node. I want to know how the terminal node joins the network. Is it through the router or directly connected...
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]
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]
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]
A biped robot joint constructed by pneumatic artificial muscles is introduced. The joint uses the flexible characteristics of pneumatic artificial muscles to effectively control the impact of the la...[Details]
In the field of software development, the most critical but also the most unpredictable phase is the debugging phase. There are many factors that play a role in the process of software debugging, a...[Details]
This issue will briefly introduce the test related to spectrum - occupied bandwidth.
Definition: Occupied bandwidth refers to the bandwidth corresponding to 99% of the total transmitted power, cent...[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]
The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[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]
