In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
Power management solutions for today's portable application processors are becoming increasingly integrated. Total power consumption, standby and sleep current consumption affect battery size, bill...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
At very low temperatures, certain metals and alloys lose their resistance to electric
