number of wealthy DB values that are actually received by the receiving station device compared to the minimum receive threshold (device reception sensitivity) allowed by the receiving station device.Sfm= Rss-rsRss= Receive signal strengthrs= device Receive sensitivity (DB)In the above example, if the device receives a sensitivity of -81DBI, the link system headroom is:Sfm=rss-rs=-70-(-) 81=11dbThe above example is that the use of this transmission power of 20dBm, receive sensitivity of -81DBI

information transmission channel. All wire slots and related connectors are certified by ISO, each channel must use special instrument to test the link impedance and attenuation rate to ensure its electrical performance. The application system wiring all uses point-to-point end-to-end, any link fault does not affect other link's operation, this has provided the convenience for the link operation maintenance and the breakdown overhaul, thus guaranteed

the requirements of TSB-67 standard, four parameters, including wiring diagram, length, attenuation, and near-end crosstalk, should be included in the verification Test index of the structured cabling system. ISO also requires an additional parameter, ACR (attenuation to crosstalk). In view of the current development trend of the network and the gradual popularization of line six, Tia has made a supplement

The on-site test of optical cable construction is very important. It is used to prepare for the overall commissioning of the optical terminal. The optical fiber test items in the optical fiber have the measurement of transmission attenuation. for Multimode Optical Fiber, test the baseband response when necessary. The purpose of the single-disk optical cable test is to ensure the quality of the factory products. the test after the construction deployme

factors determined by the light to the soft degree of the object. 3. Brightness: Light of the bright degree. 4. Color: The color property of the light source. 5. Attenuation: The intensity of the unit area of light produced by the Yuguangpo of radioactivity gradually weakens. 6. Occlusion: During the propagation of light, the phenomenon of shaded regions is caused by the blocking of objects. 7. Color temperature: In 19th century, British physicist Wi

Change the color as needed. 2. Increase the brightness by a bit. Set the gloss to 0.85. Reduce the intensity by a little. glass: 1. Adjust glass reflectivity 2. Adjust

In real life, the point light source degrades with distance. For example, a light bulb emits bright light near it, and the light in the distance is weak. In this section, we add an attenuation factor to the diffuse reflection and highlight based on the previous optical formula. The attenuation of the light source with distance is not purely linear. the commonly used formula is: DThe distance from the

the voice, the highest sound direction is the strongest, and the lowest sound is the worst .) Look at the Purple area! Upgrade 1 in 3 K Until 16 k, this is the main part of the voice of the average person (also the clearest and most nice part) if your voice is male You can adjust the gray card in the 4 K area manually, and then adjust the balance accordingly, Generally, there is no fixed preset value. Because of the different style of the Song and category, the adjusted value should also be dif

Audio editing tutorial (cool edit)-reverb parameter! [Liupin] cooledit's audio editing software is really good. No wonder a software can support a large group of people. Now we have an open-source audio processing software, audacity. I am also a member of the feature development. This software also has many highlights. You can pay attention to it, more importantly, you can learn the source code. Reverb Hall 1 simulates the reverb effect of a large concert hallParameter value range desc

The second chapter of reading notes adds to the understanding and complement of many bloggers.The second chapter is also the basic knowledge, supplemented the BO master many knowledge gaps.This paper introduces four types of light illumination models, point light source, surface light source, directional light, Spotlight, and their illumination model, and also briefly introduces the lower GI.Several topics of this chapter:1. Ideal Spot Light2. Geometric attenuation3.
