[introduction] say simply, hand in hand in transducer to need to use too much cell, bad to control, and hand in make use component continuously little, control is simple, use mostly at present so hand in the transducer that makes a structure continuously. Say simply, hand in hand in transducer to need to use too much cell, bad to control, and hand in make use component continuously little, control is simple, use mostly at present so hand in the…
[introduction] develop in height of science and technology today, automata and detect automatically the daily life in people and the proportion that industrial control holds are heavier and heavier also, make the life of people more and more comfortable, the efficiency that industry manufactures is taller and taller. And sensor is the important composition component in automata, it is the important part that information collects a system, the signal that suit to carry through be being measured what sensor…
[introduction] each attribute parameter that this type included in model of our commonly used village cropland capacitance, the temperature voltage that we introduce village cropland capacitance below and precision attribute regulation introduce. We included each attribute parameter of this model in model of commonly used village cropland capacitance, the temperature voltage that we introduce village cropland capacitance below and precision attribute regulation introduce. Temperature character expresses as follows: 1, capacitance change provision is 50…
[introduction] some medical apparatus and instruments basically uses drive board and control plate unit of two big main control is comprised, use at controlling high-energy glow and classics skin to stimulate two big functions. In carry out electrostatic discharge (±8KV of discharge of ±6KV of ESD contact discharge, air) , pulse group (±2KV) wait for electromagnetism when compatible experiment, the drive that controls high-energy glow board occurrence restoration breakdown. In carry out install compasses compression to experiment (experiment voltage 4kV)…
[introduction] our ultimate goal is to want to reduce output ripple to sustainable level, reaching the means of settlement with this the most primary purpose is the generation that should avoid ripple as far as possible, want to understand reason of the sort of ripple of switch power source and generation above all. The generation of ripple of switch power source Our ultimate goal is to want to reduce output ripple to sustainable level, reaching the means of…
[introduction] spoken parts in an opera of high frequency circuit is radio circuit, but do not involve microwave circuit (microwave is used at handling circuit of one hertz above, want the electromagnetism field proceed with from physics, with us common circuit is very different) , use at radio wave to blast off, receive, modulation, demodulation, enlarge is waited a moment. One, high frequency circuit introduces Spoken parts in an opera of high frequency circuit is radio circuit, but…
[introduction] when RF engineer is designing the impedance of chip and nature space to match, undertake matching designing according to the parameter of data manual, ultimate test discovers the function of actual result and manual to be widely divergent, why had you considered to you can appear so big difference? Match the capacitance with the different attempt in debugging a process, inductance, solder back and forth yuan of parts of an apparatus, such debugging can we improve the method? …
[introduction] the grid that insulation field effect is in charge of and source extremely, grid is mixed segregation of SiO2 insulation layer all is used between leakage pole, get a name because of this. It is metallic aluminium because of grid again, reason calls MOS canal again. Its grid – the resistor between source pole is gotten greatly than canal of knot field effect much, can amount to 1010Ω above, because it compares knot field effect,still provide temperature stability good,…
[introduction] noise signal has two kinds of main forms, also namely periodic signal and aperiodic signal. Periodic signal every sampling paragraph spectrum is same, so its spectrum shows disperse model, but strength is great, call tape noise normally; Signal of cycle of and rather than every sampling paragraph spectrum is different, its spectrum is very broad, but intensity is weaker, call broadband noise normally. The periodic signal on circuit board is the signal with generation the strongest radiate, the concussion…
[introduction] a lot of normally by the equipment of batteries power supply need charges variously composition of chemistry of power source, batteries, voltage and electric current. For example, appear as the group of new-style big batteries that suits chemistry of all type batteries to comprise, the high-end spending with substantial function, medical treatment, industry and circuit of car batteries charger need taller voltage and electricity. However, in the light of numerous input voltage, charge voltage and demand of charging…
