Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[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]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[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]
Conventional ECG recorders are one of the main means for doctors to diagnose heart diseases, but they can only record short heartbeats. In many cases, it is difficult to record ECG changes during a...[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]
Due to the needs of medical development, in many cases, general thermometers can no longer meet the requirements of fast and accurate temperature measurement, such as measuring human body temperature ...[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]
In the future, a complete automobile safety system must fully combine gyroscopes, accelerometers, steering wheel and brake pedal position detectors, and tire speed detection systems to accurately ...[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]
Broadband services supporting triple play voice, video and data are evolving for first mile customers (small businesses and homes). A key factor in this FTTx evolution is GPON (Gigabit Passive Opti...[Details]
This article will discuss a common problem in wireless mobile data reception.
Problems facing RF receivers
