How to Use FFT

FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone calls, radar measurement speed and direction, and

2 cameras running the same time

Http://forum.unity3d.com/threads/44911-2-cameras-running-the-same-time 1: Two camera instances are displayed on one screen at the same time. It is certainly possible to have multiple cameras at once. There are a couple things to know that will help with this: -Cameras have a "depth" property. This determines which orderCameras will draw. The camera with the highest depth will draw on topOf the camera with the lowest. -Clear flags are important when dealing with multiple cameras. ThisBasi

HLA Simulation Data Distribution Management

Data Distribution Management Data Distribution Management is based on some requirements in simulation. For example, in the air defense simulation, the ground radar only needs to know the air condition data within a certain range, therefore, the simulation members of the aircraft only need to transmit the data in the specified region to the radar members according to the data requirements of the ground

After the British invented the radar, they found a big problem in application: on the radar screen, they couldn't figure out which planes are enemies and who are themselves. As a result, they installed the identification system (identificationfriendorfoe, IFF) on the plane and installed the corresponding identification device (secondary rad

Engineering legends-flying pig

There is an article on the Air Force's wing website that adds wings to pig. The title party is very serious. In fact, the content is very serious. It is about the inside and outside of the stealth plane. The first generation of the stealth aircraft was F-117's nikhthawk, which was indeed thunderous. It is hard to imagine that something like this can fly and fight. To some extent, it looks really a bit like a pig with wings. The life of F-117 is also legend. At the time of its development, its co

starting to be used in the broader marketplace. System: Lane departure alarm sensor: Camera When a vehicle leaves its driveway or approaches the edge of the road, the system emits sound alarms or action alarms (via a slight vibration steering wheel or seat). When the vehicle speeds exceed a certain threshold (for example, greater than 55 miles), the vehicle does not turn on the turn signal, and these systems will begin to play a role. When a vehicle travels, its position relative to the

was a pity that in the actual combat, automotive people were still not dominant. In the early days, automotive people were running on the ground, and most of them were flying in the sky. the backbone of automotive workers is the packing cart (Optimus Prime), Van (TIN), road pioneer (Jeep), civil car (Jazz, Jack, Bumblebee ....), To put it bluntly, it is a group of civil facilities. let's take a look at the earliest backbone ion beam guns (Wei zhentian), F15 (red spider), and

transmission speed and MAC layer efficiency are improved, so the network capacity will also increase; however, only by correctly planning the distribution of network customers can the increased capacity be fully utilized. Background The Background Environment for deploying a wireless LAN is very important. Neighboring access points or other wireless transmitters that use the same frequency band may interfere with the network. This type of wireless congestion will lead to packet loss, slow netwo
