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]
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]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[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]
DC regulated power supply is a commonly used electronic device, which can ensure stable output voltage when the grid voltage fluctuates or the load changes. A low ripple, high-precision regulated p...[Details]
