Abstract: Photonic crystal fiber stability of the sensor in practical engineering applications, has an important influence. This paper analyzes the photonic crystal fiber optic pressure sensor of the basic principles introduced photonic crystal fiber optic pressure sensor system components, from the theoretical analysis of the sensor system relative to the light source wavelength, the output sig...

1 pull-up resistor (1) When the TTL circuits drive COMS circuits, if the TTL circuit output of the high is lower than the minimum high COMS circuits (typically 3.5V), then you need to TTL The output termination pull-up resistor to improve the high output value. (2) OC gate pull-up resistor must be added in order to use. (3) to increase the output pin drive capability, and L6506D datasheet and some also ...

Overall debugging is to ensure that the machines technical specifications and NE575N datasheet and design requirements, to describe the various static and NE575N price and dynamic debugging circuit assembly with the related unit test, debug circuit to solve the unit can not solve the problem. (1) six superheterodyne radio static debugging six superheterodyne radio circuit shown in Figure 5--27 shown. Adjustment is the DC current me...

DC-DC converter is installed scattered in the PDP TV power supply board, main board, logic board and DS26LS31MJ datasheet and other panels are DC-DC converter can be found in the figure. As the DC-DC converter to take the TV signal processing circuitry of a small task, therefore, prone to failure in the work. As maintenance personnel, to be able to quickly find the location of DC-DC converter, the correct measurement of...

fourth, the management of urban traffic intersection red, green cross the street in the city traffic junctions, have placed a variety of red, green high-brightness LED pattern composed of instructions for the management of motor vehicles, non-motorized vehicles and IRL3103 datasheet and pedestrians, to enable safe smoothly through the intersection of their road. The traffic light pattern, varied. The author in...

Contain metal atoms and SI9953 datasheet and the conjugated structure of conjugated polymers is a metal atom occupies a central position in the molecular plane chelate. Figure 6.113 is plotted together the chemical structure of copper phthalocyanine force, its volume resistivity | 0. To 5 10-8 ~ 0.2 (Q.cm). Maps of the central metal atom of copper (Cu), can also be replaced by magnesium (Mg), beryllium (Be) and SI9953 price and other...

(1) Select plate CCL selection will directly affect electrical performance and MT8994BC datasheet and service life. In the design of printed circuit boards, should be based on the products electrical and MT8994BC price and mechanical properties and MT8994BC suppliers and the use of the environment use different CCL. Mainly based on: whether the heating circuit components (such as high power components) and the circuits operating frequency; structural requireme...

With the extensive application of digital integrated circuits, the test system becomes increasingly important. Reliability test of integrated circuits in the network and LT1638CDD datasheet and test system project, the need to test some level with a wide range of military digital integrated circuit chip, while the common market of small and LT1638CDD price and medium-level test system can be measured mainly the range, and LT1638CDD suppliers and large-scale te...

In the design of printed circuit board, to consider the problem of interference, if the circuit schematic design is correct, properly printed circuit board design, the reliability of electronic equipment will have a negative impact. In the design, use of anti-interference measures, many of them commonly used measures are the following three: (1) ground, the power line design In electronic devic...

As the silicon diode and CD74HC4040E datasheet and germanium diode forward voltage drop different tubes, so you can measure the resistance of the diode forward way to be distinguished. Method is to use multimeter R lk block to measure the diode forward resistance. If the forward resistance is less than 1k \ Q,, compared with germanium diodes; if the forward resistance of 1 ~ 5kCl,, compared with silicon diodes. general ...
