Distributed amplifiers can provide a wide frequency range and high gain. For a while, their design usually used transmission lines as input and output matching circuits. Bill Packard (one of the found...
Yesterday, the homepage of China Mobile's M-Zone website was tampered with, turning into a completely black interface with a line of red text that read "Please ask China Mobile to make the phone bills...
[size=5] When I compiled it in CCS5, it said that csl.h could not be found. When I transferred it to CCS3.3, it said that the _CACHE_clean symbol was undefined, but there was no prompt that csl.h coul...
The traditional method uses Taylor series expansion and then multiple iterations. The disadvantage of this method is that it requires division and is not fast. Is there any other trick to achieve this...

This paper designs a 16x16LED Chinese character display bar based on single-chip dynamic scanning control, briefly analyzes the principle of Chinese character display, and studies how the LED displ...[Details]
The emergence and development of street lamps are inseparable from the prosperity and progress of cities, which makes street lamps useful. Conversely, street lamps also make the night of the city n...[Details]
Dual Tone MultiFrequency (DTMF) signaling is gradually being used in push-button telephones around the world. It quickly replaced the dial pulse signaling used in traditional rotary phones because ...[Details]
In the 1980s, breakthroughs were made in the design and production of small, low-power quartz metal halide lamps with precise dimensions. At the same time, with the acceleration of people's lives a...[Details]
Voltage hysteresis is a characteristic of lithium-ion battery and the basis of its existence. The principle is as follows: the thionyl chloride electrolyte of the battery is a strong oxidizing chem...[Details]
Any power transmission and distribution equipment and power-consuming devices cannot be pure resistive loads, so they must occupy a certain amount of reactive power. The existence of reactive curre...[Details]
Today's advanced electronic systems for the telecom and datacom markets rely heavily on high-performance, fine-line digital ICs (FPGAs, DSPs, and/or ASICs) to quickly and efficiently process time-s...[Details]
3. Driving circuit design
The power driver uses a field effect tube, which is a field-controlled device with a capacitance effect between the gate and source, so it has high requirements for t...[Details]
In the process of instrument application, there are many types of influencing factors of online gas analyzers and the changes are more complex. It is difficult to effectively control these influenc...[Details]
introduction
In industrial production and equipment maintenance, people often test coil winding turn-to-turn short circuit faults. For example, turn-to-turn short circuits in power transformer...[Details]
The high-pressure common rail system consists of a high-pressure fuel pump, a common rail, an injector, an electronic control unit (ECU) and various sensors. The low-pressure fuel pump inputs the fuel...[Details]
