[introduction] about crystal oscillator, its English name is Quartz Crystal Oscillator, namely the brilliant that we often say brace up, of course cough up, also have call its active brilliant brace up. It can produce central processor (CPU) executive instruction place must clock frequency signal, the execution of all CPU instructions is to build what go up in this foundation, clock signal frequency is taller, the traversal speed of CPU is normally faster also.   If include the electronic product…

[introduction] the article is with stimulating formula switch power source instead exemple, elaborated its to conduct in all mechanism of the generation that the model disturbs, transmission. According to the thought that active node balances noise, put forward a kind of new transformer EMC to devise a method.   The article is with stimulating formula switch power source instead exemple, elaborated its to conduct in all mechanism of the generation that the model disturbs, transmission. According to the thought that…

[introduction] electronic equipment must use direct current source, receive power source most those who be afraid of is negative pole is received turned over. If was not prevented,receive circuit instead, that does not know to be able to produce what situation, component damages that is affirmative. So general circuit can be added receive circuit instead, introduce a few kinds of commonly used circuit as follows.   Electronic equipment must use direct current source, receive power source most those who be…

[introduction] end is inputted in alternating current source, general need increases 3 safe capacitance to restrain EMI conducted interference. Alternating current source inputs cent to be 3 terminal: Live wire (L) / 0 lines (N) / ground wire (G) .   Restrain with 0 lines in live wire between shunt-wound capacitance, say commonly for X capacitance. Because position of this capacitance connective also compares a key, same need accords with relevant and safe level. X capacitance also attributes one of…

[introduction] a sensitive to sound capacitance type is stationed in the buy inside sensor extremely body mike. Sound wave makes inside mike halt extremely body film is oscillatory, cause the change of capacitance, and the tiny voltage that generation changes to meet an emergency to it. This one voltage is changed into the voltage of 0-5V subsequently, through A/D changeover is collected by data implement accept, convey the computer. It is used receive sound wave, image of indication audio vibration….

[introduction] photoelectricity diode is the semiconductor that use can take theory, when diode of smooth illuminate photoelectricity, when smooth energy is more than belt unoccupied place energy, the electron that valence electron takes is led campaign by incentive guide, original valence electron leaves hole. Reach depletion layer to produce an electron in P area, N area so – hole is right.   1, the principle is different Photoelectricity diode is the semiconductor that use can take theory, when diode of…
