[introduction] in June the Shanghai of end, the sky is falling drop drop spit, however the enthusiasm that a bit cannot hold back people! By cruel curtilage science and technology and the intelligence of “ whole world that net of OFweek intelligence hardware sponsors jointly change accelerator to embrace science and technology to embrace prospective ” salon to was held as scheduled at 2 o’clock afternoon on June 30. June the Shanghai of end, the sky is falling drop drop…

[introduction] signal integrality is the quality that points to signal to go up in transmission method, namely signal can make response ability with correct sequential and voltage n in circuit. If circuit design can achieve a signal to be in with formulary sequential, duration and voltage amplitude,interrelate transmit in the system, show this circuit has good signal integrality. Signal integrality problem is reflected in a lot of respects, reduce fixed rate when signal rise time, when the parasitism capacitance on…

[introduction] the telegraphic date that appearance amplifier can recuperate sensor to generate, the digitlization that realizes these signal thereby, memory or use its at controlling signal general and lesser, accordingly, amplifier may need configuration to be tall gain. Additional, signal may be folded increase in all modular voltage, likely also larger straight prediction of a person’s luck in a given year moves overlay voltage. Accurate instrument amplifier can provide tall gain, magnify two input the difference between voltage optionally, check…

[introduction] in industrial spot, because the sensor of quantity of of all kinds imitate such as pressure, displacement, temperature, discharge, rotate speed designs use technics to differ. Main component is made for two lines and 4 lines make the way of sensor job distribution, the imitate signal that its output also has difference each, and have signal of voltage of signal of electric current of 0-20mA, 4-20mA and 0-75mV, 0-5V, 1-5V commonly.   Want to collect signal of imitate of…

[introduction] portable apparatus is faced with a lot of and potential electromagnetism to disturb (EMI)/ radio frequency is disturbed (the risk of RFI) source, like voltage of switch load, power source amplifier of power source of fluctuant, short circuit, thunder, switch, RF is mixed the high frequency noise of power amplifier and clock signal. Accordingly, circuit design and electromagnetism compatibility (the technical level that EMC) designs is mixed to the quality of the product the effect that specifications index will…

[introduction] the environmental perception sensor that automatic road-sense involves basically includes a visual sense kind camera (include only item, binocular and stereo vision, panoramic vision and infra-red watch for a chance) with radar kind range finding sensor (radar of lidar, millimeter wave, ultrasonic radar, if pursue,1 is shown. These sensor can find the SDK of the source to be developed quickly at present. Small but the development experience according to these a few years, arranged a few API of current…

[introduction] the core component of enlarge circuit is dynatron, want to want to have certain knowledge to dynatron so. The sort of the enlarge circuit that makes with dynatron is more, we come with a few commonly used kinds explanation (the 1) that be like a graph. Graph 1 it is the basic enlarge circuit that altogether shoots, general some of what content do we master to magnifying the road wants?   The core component of enlarge circuit is dynatron,…

[introduction] most electron yuan the input power supply that parts of an apparatus needs to come from AC power line. For component of downstream to power source of mode of voltage manostat, switch and other electron, a complete bridge or parts of an apparatus of commutator of half bridge diode are undee to sine AC voltage undertake rectification, it is its changeover voltage of a DC.   4 diode in configuration of use bridge-type commutator are what undertake rectification to…
